Key Discussion Points & Insights

1. Identifying the Scriptural Connection

• Direct Fulfillment in the New Testament:
  • Luke’s Gospel quotes Isaiah 40 directly, making the fulfillment of prophecy unmistakable.
  • "We obviously know that the passage from Luke fulfills the Isaiah 40 passage because it directly quotes it and tells us explicitly that it’s being fulfilled." (Beth, [00:54])

2. Role of John the Baptist: The New Isaiah

• John as Fulfillment and Continuation:
  • John the Baptist is not just the prophesied “voice in the wilderness,” but also serves as a new Isaiah, echoing both judgment and hope.
  • He prepares the way for Jesus, calls people to repentance, and baptizes for the cleansing of sins.
  • "John as well is a prophet who is in the wilderness. And he is proclaiming judgment. He’s calling people to repentance...he’s also proclaiming hope." (Beth, [01:21])
• Parallel to the Prophetic Role:
  • The hosts draw out how John’s prophetic message and actions are a sign that Isaiah’s prophesied time has arrived.
  • "There’s a new Isaiah, a new messenger, and this one is proclaiming the imminent arrival of the Lord." (Beth, [01:21])

3. Jesus’s Baptism: God Among Us

• Fulfillment Personified:
  • Jesus’s baptism is not just the arrival of the messenger, but also the arrival of God Himself—the ultimate fulfillment of Isaiah’s message.
  • "The Lord Himself is here. And so this is why I said yesterday that the triune nature of God...is so important, because Jesus has come. He is the Messiah. He is the true King of Israel." (Beth, [02:20])
• Highlighting Christ’s Divinity:
  • Jesus is not simply a chosen man or a prophet; He is God incarnate, the eternal Son, and part of the Trinity.
  • "He’s not merely a man that was just chosen by God to be his representative...He is God Himself. He is incarnate. He is God become flesh." (Beth, [02:20])
• Manifestation of God’s Glory:
  • The prophecy of God’s glory appearing to Israel comes to fruition through the person of Christ at His baptism.
  • "That prophecy that Isaiah spoke, the glory of the Lord, has now appeared to Israel, just like Isaiah said it would." (Beth, [02:20])

4. Awe at the Unified Storyline

Transcript

[A]

Welcome to A Year in the Bible with daily grace. This year we want to spend a few minutes with you every day walking through our study Christ in All of Scripture. Each week we will dive deeply into two passages of Scripture, one from the Old Testament and one from the new, seeing how they connect and point to Jesus.

[B]

Whether you are doing the study yourself or just following along with us here, we are hopeful that through studying these passages each week, you will see how Christ is not only present throughout the entire biblical story, but but the center of it.

[A]

Hey friends. Welcome back to A Year in the Bible. My name is Beth and I am here with my co host, Alexa.

[B]

Hey everyone. We are excited to have made it to another day of Christ Connections. So today we'll be looking at our two passages, Isaiah 41:5 and Luke 3:1:6 and verses 21:22. And we're going to talk about how they both connect to each other and to Christ.

[A]

So we obviously know that the passage from Luke fulfills the Isaiah 40 passage because it directly quotes it and tells us explicitly that it's being fulfilled. But I do want to talk about how it is being fulfilled in two particular ways. First through the message of John the Baptist and then also through the announcement that's made by God at Jesus's baptism.

[B]

Yeah, I'm super excited about this, Beth. So tell us first how Isaiah 40 is fulfilled through John the Baptist.

[A]

So we Learned from Luke 1 that John is actually Jesus's cousin and that he was sent to fulfill this message by preparing the way for the Lord in the wilderness. What is so cool about John's role is that he not only fulfills the message of Isaiah, he also functions like a new Isaiah. And so John as well is a prophet who is in the wilderness. And he is proclaiming judgment. He's calling people to repentance. He's saying that you are a sinner, but he's also proclaiming hope. He's saying, be baptized, come and be cleansed and be washed. And so through John's message, the people of Israel were shown that the time of Isaiah's prophecy is actually here and that it's about to be fulfilled. There's a new Isaiah, a new messenger, and this one is proclaiming the imminent arrival of the Lord.

[B]

Those parallels are just really cool, Beth. So thanks so much for pointing that out to us. It's, you know, it's connections like that that just leave me in awe over how the New Testament fulfills what we see in the Old Testament. Okay, what about Jesus's baptism?

[A]

Yeah, Jesus's baptism reveals that it is not just the messenger from Isaiah's prophecy that has arrived, but also the fulfillment of the message itself. The Lord himself is here. And so this is why I said yesterday that the triune nature of God that we talked about is so important, because Jesus has come. He is the Messiah. He is the true King of Israel. But he's not merely a man that was just chosen by God to be his representative in the way that the kings of the Old Testament were. He is God himself. He is incarnate. He is God become flesh. And so, yeah, he's come in human form. Jesus is God's eternal Son, part of the triune nature of God. He's one with God himself. Which means that that prophecy that Isaiah spoke, the glory of the Lord, has now appeared to Israel, just like Isaiah said it would.

[B]

Man, that's just so good. And when a testimony to God's faithfulness, as we've been talking about, you know, hundreds of years later, God has revealed his glory through the person of Christ. You know, these are just the moments that make me excited to study God's Word. Well, friends, that is all for today, but we hope that you join us tomorrow as we close out this week talking about application.
