The Exodus, the Babylonian captivity, the birth of Jesus, the cross of Jesus, the resurrection of Jesus. These are decisive moments that define all of history. And supremely, the birth of Christ occurs as a chirotic moment in the fullness of time. It comes to pass after centuries and centuries and centuries of prophetic promise and of patient waiting by the people of God.

The birth of Christ, the incarnation, it was a real event that really happened in history, and it cannot be overstated how important that truth is. And one of the ways Scripture speaks of this monumental historical event is, is that Christ came in the fullness of time. Welcome to the Monday edition of Renewing youg Mind. I'm your host, Nathan W. Bingham. Today, R.C. sproul begins his series, Coming of the Messiah. Over the course of the week, Dr. Sproul will closely look at a few of the most important messianic prophecies of the Old Testament.

To begin this week's series, Coming of the Messiah.
A
As we prepare this year to celebrate Christmas, we're going to spend a few days looking at some of the important texts of the Old Testament that predicted the coming of the Messiah. So as we contemplate the advent of Christ, which means his coming to the world, we want to do it in terms of how Christ fulfilled the Old Testament promises of his coming. Now, before we actually look at those Old Testament prophecies of his Advent, I want to begin today by looking briefly at the beginning of the Christmas narrative itself as we find it. In the second chapter of the Gospel According to St. Luke, the Christmas story begins with these words, Luke 2:1. And it came to pass in those days that a decree went out from Caesar Augustus that all the world should be registered. This census first took place while Quirinius was governing Syria. So all went to be registered, everyone to his own city. Now, we're all familiar with that introduction to the narrative of the birth of Jesus. But what I want to look at today is the references to this birth as they are placed concretely in the context of real history. The opening words of the story are these. And it came to pass. Now we have to understand initially the difference between history and fairy Tale. The classic beginning of fairy tales in children's literature is the opening line that goes like, once upon a time. And we use that particular preface to create a setting that is really nebulous, amorphic, and uncertain with respect to any specific time period. Because the time period really doesn't matter for fairy tales or for myths. But one of the things that we're concerned about when we look at Jewish literature is the commitment of the Jewish people to an understanding of a redemption that takes place in history. Now, I understand that in our day, there have been all kinds of attempts by critical scholars to dehistoricize the Scriptures and to rip the Scriptures out of their historical setting or to identify the Scriptures with a particular type of mythology. We remember Rudolf Bultmann, who's one of the most important New Testament scholars of the 20th century, this German scholar, who said that for the Bible, and particularly the New Testament, to be relevant to modern people, we must approach the task of interpreting the Scriptures by using a method that he called demythologizing the Bible. He said that the Bible is essentially a book of myths. And nevertheless, at the core of the mythological structure of the Bible is a small kernel of what he calls history. And so it's the task of the modern person to peel away the husk of mythology in order to reach that kernel of real history. Bultmann also took the position that redemption itself, salvation, is really not a historical event. As such, the real history of the New Testament doesn't give us the truth about Jesus, but rather gives us the reflection of the faith of the people who wrote about him in that particular period. The faith of the early church is a matter of historical record. The object of the faith of the early church, however, is steeped in mythology. Others have tried to show parallels between Greek mythology, for example, and the New Testament portrait of Jesus. I remember teaching a class in philosophy many years ago in a college setting, and my students kept coming up with all kinds of questions about the mythological foundation of the New Testament. And I thought these questions were somewhat sophisticated. And I wondered what. What was provoking this rash of questions? And so I asked them in class. I said, why are you asking me all these questions about Greek mythology? And they answered by saying that their literature professor had been teaching them a course in the humanities, and they were studying Ovid's Metamorphosis. And in Ovid's poetic work, there are frequent references to dying and rising gods and mythological events surrounding the mythological deities of the day. And the literature professor was laboring the point of trying to show the parallels between Greek and Roman mythology and the New Testament. So this professor was a friend of mine, and we went to the snack bar at the student union building one afternoon, and I asked him about all of this, and he said, yes, he was making those comparisons in his class. And I said, well, while you're doing it, I said, are you also pointing out the difference between the Greek mythological literature and the literature of the New Testament? And he said, well, what differences are there? And I said, well, perhaps the most important difference is the fundamental difference between the Greek understanding of history and the Jewish understanding of history. To the Greek, there was no real attempt to ground the stories of their gods and goddesses in real time and space. They understood that the myths were precisely that myths. But the Jewish claim in Jewish literature was that the actions of God about which they were writing were true historical events. And in fact, to the Greek, it would be scandalous to have God become physically involved in any way with real history. One of the things that we often overlook is that the real scandal about New Testament Christianity to Greek thinking was not so much the resurrection of Christ as it was the incarnation, the idea that God would ever contaminate himself by taking upon himself a physical body in any way because of the prevailing influence of Platonism in Greek thought that saw anything physical as being inherently imperfect. And it would be beneath the dignity of God to be engaged in any way in incarnation. But beyond that, one of the dominant motifs of Greek thought was the motif of a cyclical view of history, a cyclical view of history, which means that there is an eternal recurrence of human events, that history has no beginning, that the universe as such is eternal, and history moves in a continuous circle. And circles have no definitive beginning and no specific point of termination. And over against that is the Jewish view of history, which, in distinction from the Greek view of history, was linear. That is, the Bible begins on the very first page by speaking of what a beginning. In the beginning, God created the heavens and the earth. That's the primary assertion of the literature of the Old Testament, that redemption is not even dealt with until first of all, it's established that there is a creation, that history has a beginning point, but that history not only begins, but it moves towards a point of consummation. Now, let's talk about that for a few minutes. In light of this statement of Luke at the beginning of his Gospel, when he describes the narrative of the birth of Jesus, he says, and it came to pass. What he's saying is something happened and that which happened, happened in time and space. Something happened that he recorded that he had indicated already earlier in the preface to his gospel, that he had undertaken his own research, interviewing eyewitnesses of these accounts, and so on. And so the affirmations that he is making are affirmations of history. He said, it came to pass in those days that a decree went out from Caesar Augustus. And then in the next sentence, he says, this census took place while Quirinius was governing Syria. So the setting for the birth narrative of Jesus is placed squarely in the context of real secular history, if you will, because there really was a Caesar Augustus, and there really was a Quirinius, there really was a Rome, and there really was Assyria. And so Luke's assertion about the birth of Jesus is, in a sense, already demythologized. It's already set directly in the context of history. Now, a word that is used frequently in the New Testament with respect to the events that transpire that are told of there is the Greek word pleroma. And that term, pleroma, is usually translated by the English word fullness. And we hear the expression subsequently in the New Testament regarding the fullness of time. Now, to understand that, I want to back up into another little abstract study, if you will, remembering Bultmann, who I mentioned a few moments ago, who wants to demythologize the New Testament. Bultmann argued that salvation as such is not something that takes place in history, but it is something that takes place in what he calls the eternal now. Or to be just a little bit technical for a second, he speaks about redemption occurring in the hic et nunc. And if you know your Latin, remember it means the here and the now. And redemption is something that happens instantly, suddenly, immediately and vertically. To use his expression, redemption takes place directly and immediately from above, when a person has kind of an existential experience of encountering the meaning of Jesus in a vertical existential event that is not something that happens on the horizontal plane of history. Hence he calls his theology a theology of timelessness for the express reason that he rips the concept of redemption out of the foundation of chronological history. Now, Bultmann's challenge to New Testament scholarship created a furor in the 60s and 70s, particularly on the continent of Europe. And one of his chief critics was a Swiss scholar by the name of Oscar Kuhlmann. Kuhlmann wrote three books in which he critiqued the Bultmanian school of biblical interpretation. The trilogy involved his very important Christology of the New Testament and his work Salvation in history, where he demonstrates that in Jewish categories, the context for salvation is always real history. But the book I'm most concerned about to mention briefly now is his book that perhaps catapulted him to international fame, that that was entitled Christus Unterzeit. Christ and Time. Christ and Time. Now, what Cullmann did was this. He carefully examined all the time frame references of the New Testament and examined them not only in terms of the Greek antecedent meanings of the words that were used, but also in terms of the Jewish import of these ideas. And so he carefully examined words like day, hour. How many times, for example, do we encounter Jesus speaking about his hour? My hour has not yet come, or the hour has come and now is. And he speaks with those kinds of time frame references. And Cullman noticed, of course, that in the Greek world and in the Greek language, there are two distinct words in Greek, both of which are and may be translated into the English by the word time, time itself. And those two words are the words chronos, C H r o n o s and kairos, K A I r O s And he saw enormous significance in this distinction that is found in these Greek words. And let me take a minute to explain that to you. The word chronos, C h r o n O s is a word with which we're familiar. We have some newspapers that are called chronicles. We have these little instruments that we wear on our wrists that we normally call watches or wrist watches, but sometimes more technically are referred to as chronometers because they meter means to measure, they measure time. And so what he says is that the word chronos refers basically to the normal moment to moment passing of time that takes place as an integral part of our experience. We are creatures who live our lives in this horizontal plane of moment by moment passing of time. We have a chronology to our lives so that everything that takes place takes place, anything real that takes place takes place within the context of chronos. Now, the word kairos is a little tougher to get a hold of because we don't have an exact word that completely captures this Greek word kairos. The word kairos in the Greek refers to a specific particular moment in time that is of extraordinary significance. It's not something that takes place outside of time, but it takes place within the broader flow of time. It is a point within chronos that defines the meaning of all time. Now we have a distinction that comes close. We make a distinction between historical and historic. Everything that ever happened is historical, isn't it. But we don't use the term historic to refer to every event that ever took place. But we think of 1492 as a historic year because Columbus discovered America or 1066 was historic because of the significance of the Battle of Hastings and 1776 and so on. And we try to say there are certain events that take place in time that are of crucial meaning. And the Jew, when he writes of his history, doesn't just give us the whole chronicle of world history, but is a concern to speak of those chirotic moments in time, those particular meanings of time that are pregnant with significance. The Exodus, the Babylonian captivity, the birth of Jesus, the cross of Jesus, the resurrection of Jesus. These are decisive moments that define all of history. And supremely, the birth of Christ occurs as a chirotic moment in the fullness of time. It's not something that happens instantly, like Athena being born de nova from the head of Zeus, but it comes to pass after centuries and centuries and centuries of prophetic promise and of patient waiting by the people of God. And what we're going to do then is give a brief look at some of the Old Testament historical background that looks forward to the future chirotic event of the coming of Christ to the world.

Title: In the Fullness of Time
Podcast: Renewing Your Mind by Ligonier Ministries
Date: December 22, 2025
Host: Nathan W. Bingham
Guest Speaker: Dr. R.C. Sproul
This episode introduces Dr. R.C. Sproul’s series “Coming of the Messiah,” focusing on the historic reality and theological significance of Christ’s birth. Dr. Sproul emphasizes the differences between the historical grounding of Christianity and other religious or mythological systems, explaining why Scripture insists that redemptive events—including Christ’s Incarnation—took place in real history at a divinely appointed moment: "the fullness of time." The conversation sets the stage for a weeklong exploration of Old Testament Messianic prophecies and their New Testament fulfillment.
[01:46–03:34]
"The classic beginning of fairy tales ... is ... once upon a time ... but one of the things that we're concerned about when we look at Jewish literature is ... redemption that takes place in history." (04:06)
[05:25–09:45]
Dr. Sproul recounts discussions with students and colleagues about biblical accounts and mythology.
Greek myths are acknowledged as fictional and set in an ambiguous, cyclical view of history.
Jewish—and subsequently Christian—views are linear: history has a beginning (creation) and moves toward a consummation.
“To the Greek, there was no real attempt to ground the stories of their gods and goddesses in real time and space ... the Jewish claim ... was that the actions of God ... were true historical events.” (08:12)
Discusses the Greek philosophical discomfort with incarnation—the idea that God would become flesh:
“To the Greek, it would be scandalous to have God become physically involved ... The real scandal ... to Greek thinking was not so much the resurrection ... as it was the incarnation.” (09:50)
[04:26–15:35]
[15:35–18:30]
Chronos: Everyday, sequential time (e.g., measured by calendars and watches).
Kairos: Significant, decisive moments that transform history (e.g., the Exodus, the Cross).
"The word kairos ... refers to a specific, particular moment in time that is of extraordinary significance ... it is a point within chronos that defines the meaning of all time." (17:46)
Biblical writers, especially Luke, situate Christ’s birth as a kairos moment, not instant or mythic, but the culmination of centuries of prophecy and waiting.
[18:52–20:47]
The birth of Christ is the supreme “chirotic moment”—a decisive event in the fullness of time, not detached from history but embedded in it.
Dr. Sproul signals upcoming episodes will explore Old Testament texts that anticipate this kairos of the Messiah’s arrival.
“The Exodus, the Babylonian captivity, the birth of Jesus, the cross of Jesus, the resurrection of Jesus. These are decisive moments that define all of history. And supremely, the birth of Christ occurs as a chirotic moment in the fullness of time.” (19:01)
On the nature of biblical history:
"The Jewish claim ... was that the actions of God ... were true historical events." — Dr. R.C. Sproul ([08:12])
On contrasts with Greek thought:
"The real scandal ... to Greek thinking was not so much the resurrection ... as it was the incarnation, the idea that God would ever contaminate himself by taking upon himself a physical body ..." — Dr. R.C. Sproul ([09:50])
On the meaning of kairos:
"The word kairos ... refers to a specific, particular moment in time that is of extraordinary significance ... it is a point within chronos that defines the meaning of all time." — Dr. R.C. Sproul ([17:46])
On decisive moments in redemptive history:
“The Exodus, the Babylonian captivity, the birth of Jesus, the cross of Jesus, the resurrection of Jesus. These are decisive moments that define all of history. And supremely, the birth of Christ occurs as a chirotic moment in the fullness of time." — Dr. R.C. Sproul ([19:01])
Dr. Sproul’s teaching unfolds in a logical, compelling progression:
This episode sets a foundation for further exploration of messianic prophecy over the coming week, underscoring that understanding Christ’s coming requires seeing it as both promise fulfilled in history and the ultimate kairos—God’s decisive intervention in time.
