Key Discussion Points & Insights

1. Judgments Against the Nations: Context for Isaiah 19–21

• Paul explains that this section continues Isaiah’s series of judgments against various nations, with a particular focus on Egypt:
  • “We're continuing a portion here on the judgments against the nations, and we get specifically a judgment against Egypt.” (00:23)

2. The “Sign Act” of Isaiah: Prophet as a Living Message

• Isaiah’s Action: God commands Isaiah to go about nearly naked for three years. This is interpreted as a public, prophetic action (sign act) symbolizing Egypt’s future humiliation at the hands of Assyria.

  • “In verse 2 through 5, it says that the Lord commanded Isaiah to do this really weird thing, to walk around naked or close to naked... for three years. And this is an example of what's known in the Bible as a sign act, which is essentially a prophetic action that communicates something from God to the people.” – Paul (00:23)
  • Isaiah’s stripped state was a public, shocking reminder of Egypt’s coming disgrace: “Just as Isaiah was stripped and barefoot for three years, so too will the Egyptians be stripped and barefoot when Assyria attacks them.” (00:23)

• Comparison to Other Prophets: Paul likens this to Hosea marrying an adulterous woman as a prophetic sign (foreshadowing God’s message to unfaithful Israel).

3. Making Old Testament Sign Acts Relevant Today

• Modern Application: Paul draws parallels between Old Testament sign acts and how believers’ actions today can serve as living testimonies about God.
  • “If we really think about it, our lives are ultimately kind of a sign act in a way... It's an action that communicates something about God. That's basically what evangelism is, right?” (02:04)
• Examples Provided:
  • Loving enemies and praying for them serves as a powerful, countercultural sign to the world.
  • Radical generosity—giving to the church or missions—is a visible, tangible proclamation of faith that contrasts with worldly values.
• Self-Reflection Prompt: Paul poses a challenge to listeners:
  • “Would someone be able to look at my life and know that it's pointing to God in the same way that Isaiah's life for these three years pointed to God's judgment?” (02:04)
  • “The purpose of my life... is not to be happy or to have money or any of these things, but to live my life in such a way that it points to Jesus as my Savior and as our God.” (02:04)

4. Trust in God Alone: A Repeated Theme

• Shelby emphasizes a key lesson from these chapters and the ongoing judgments: the futility of trusting in human power and the necessity of putting trust in God.
  • “A takeaway that has repeatedly come to mind is just to put your trust in God alone. I think a lot of these nations put trust in the perceived power that they thought that they had... But we clearly see here that God is in control, that he is the One in power.” (04:12)
  • “Ultimately our trust is in him alone and not anything we think that we can accomplish on our own.” (04:12)

Notable Quotes and Memorable Moments

• Paul on sign acts:
  “Every time that people saw Isaiah, obviously in a very socially taboo way, they'd be reminded of this judgment against Egypt.” (00:23)

• Shelby on applying obscure passages:
  “I think you just took a passage that might leave us, like, scratching our heads and wondering and broke it down for us, made it really applicable for our lives today.” (04:12)

• Paul on practical sign acts today:
  “When we love those who hate us... that is a sign act to the world that forgiveness in Christ allows us to live a new way.” (02:04)

• Shelby on trust:
  “That is something I feel like I've just seen come up over and over as we walk through these judgments against nations.” (04:12)

Transcript

[Narrator]

Foreign.

[Shelby]

Hey, this is Shelby and Paul, and we are in Isaiah 19 through 21. We encourage you to leave a review or a comment. Let us know what you took away from these chapters that you read and studied today. Paul, Isaiah 19, 21. What is happening in these chapters?

[Paul]

We're continuing a portion here on the judgments against the nations, and we get specifically a judgment against Egypt. And we have a really interesting passage here in chapter 20 that's I think, helpful to talk about as we get into all the prophetic books. And in verse 2 through 5, it says that the Lord commanded Isaiah to do this really weird thing, to walk around naked or close to naked. He might have been wearing a loincloth or something like that, but to walk around basically naked for three years. And this is an example of what's known in the Bible as a sign act, which is essentially a prophetic action that communicates something from God to the people. So normally they prophesy in words, but occasionally God will give them specific actions. Really good example of this is the book of Hosea that we'll get to eventually where God commands Hosea to marry an adulterous woman as a prophecy of judgment against Israel, who is figured as an adulterous woman to God. And so we have an interpretation of this sign act of Isaiah in verses 3 through 4, that just as Isaiah was stripped and barefoot for three years, so too will the Egyptians be stripped and barefoot when Assyria attacks them. And so every time that people saw Isaiah, obviously in a very socially taboo way, they'd be reminded of this judgment against Egypt.

[Shelby]

Yeah, and I think those prophecies we'll also call, like show and tell prophecies. Yeah, that's a good word for future books. And so I'm glad you gave us that explanation, because that's certainly not the last time we're going to see that come up. Okay. Do sign acts have any relevance for us today? And maybe even this specifically, the one that we see here?

[Paul]

Yeah, they do seem kind of weird to us today. And I think, though, when we boil it down to its most basic form, if we really think about it, our lives are ultimately kind of a sign act in a way, if we think about it, that it's an action that communicates something about God. That's basically what evangelism is, right? That we live our lives in a certain way. And yes, that involves saying certain things, but there are certain actions that we take that communicate things about God that cause people to look at us and say, I wonder why that is. Why does he live that way. I think a good example of this is the church, right? We gather together to worship. We have baptism and communion, and we even greet visitors as they walk through the door. All of these actions are communicating something about God both to us and also to the people around us. And so I think this works as a way to kind of evaluate ourselves. Would someone be able to look at my life and know that it's pointing to God in the same way that Isaiah's life for these three years pointed to God's judgment? I think there's two things that come to mind in this regard is when we love those who hate us, we love our enemies, and we pray for those who hate us. That is a sign act to the world that forgiveness in Christ allows us to live a new way, to not be angry, to not have vengeance, but to instead love our enemies. I think about the way we spend our money to give to the church, to give to missions. For a world that really prides itself on greed and holding on to what's ours. That can be pretty radical. That can come across as pretty radical. And so I think for me, the takeaway from these sign acts is just that God uses us and our actions to evangelize the world, to communicate his truth about who Jesus is, is, and what he did for us. And so the purpose of my life, you know, is not to be happy or to have money or any of these things, but to live my life in such a way that it points to Jesus as my Savior and as our God.

[Shelby]

Yeah, that's a great way to explain that. And I think you just took a passage that might leave us, like, scratching our heads and wondering and broke it down for us, made it really applicable for our lives today. I think that gives us all a lot to reflect on, you know, as we continue moving through Isaiah and seeing these judgments to the nations. I think a takeaway that has repeatedly come to mind is just to put your trust in God alone. I think a lot of these nations put trust in the perceived power that they thought that they had. You know, their ability to maybe win a war, or maybe they want to enact judgment on one of their enemies. But we clearly see here that God is in control, that he is the One in power. And so ultimately our. Our trust is in him alone and not anything we think that we can accomplish on our own. And so that is something I feel like I've just seen come up over and over as we walk through these judgments against nations. So, okay, really appreciate the way you broke down those chapters today. Paul, thank you for that. We'll continue in Isaiah tomorrow.
