Episode Overview

Podcast: A Year in the Bible with Daily Grace
Episode: S5: Day 206: Isaiah 16–18
Date: July 25, 2026
Hosts: Shelby (A), Paul (B)

In this episode, Shelby and Paul work through Isaiah chapters 16–18, continuing their journey of reading the Bible in a year. The focus is on the theme of God's judgments against the nations—specifically Moab, Damascus, the Northern Kingdom of Israel, Cush, and, by extension, all nations. The conversation centers on the theological meaning of these judgments and their relevance for Christians today, especially considering the way Gentiles are now included in God’s promises through Jesus.

Key Discussion Points & Insights

The Nature of the Judgments (00:21–00:44)

• Paul explains that these chapters continue the section of Isaiah declaring judgments: against Moab (ongoing), then Damascus/the Northern Kingdom of Israel (notably treated like a foreign nation in this context), and then Cush—culminating in a broader judgment against all nations.
• Notably, the Northern Kingdom (Israel) is addressed as a foreign nation due to its opposition to the Southern Kingdom.

Israel, the Nations, and God’s Promise (00:51–03:19)

• Paul dives deep into Israel’s covenant relationship with God and their role among the nations:
  • Israel as God’s chosen people, with covenants unique to them.
  • The Abrahamic covenant also included a promise that "through Abraham, all the nations of the earth will be blessed."
  • Foreigners could partake in Israel’s covenant if they adhered to the law (Deuteronomy 10:18; Leviticus 24:22).
  • Crucial shift with Jesus: “But through Jesus, everything about that relationship changed.” (B, 01:57)
    • In Acts 15, it was decided that Gentiles don't have to be circumcised or follow all Jewish laws to receive salvation.
    • This opens the promise of deliverance and salvation to Gentiles, directly relating to the judgments discussed in Isaiah.
  • Key Point: "We Gentiles, non-Jews, are brought into the promise of salvation, the promise of deliverance from this very judgment we read in today’s chapters as Gentiles, not as Jews." (B, 02:49)
  • Paul highlights the paradox that, “one day most of God’s people is actually going to be Gentiles... At one point all these nations receiving judgment will be the primary people that God calls his.” (B, 03:12)

Takeaways and Application (03:19–04:53)

• Paul’s Reflection: Gratefulness for inclusion in God’s people.
  • "All of these nations were sinful, just like we are sinful. And we could very well have received similar judgments. But through Christ... we were able to be included in the family of salvation.” (B, 03:38)
  • Paul emphasizes the gift of being in relationship with God because of Christ, who received the judgment in our place.
• Shelby’s Reflection: Limitations of human wisdom and the true source of peace.
  • "All these nations had built a system, or they had built a nation that they felt would bring them peace... And yet here we see God judging them. So I think the folly of human wisdom comes to mind, and just the fact that it is in God alone that we find peace, that we find rest, that we find our true meaning and purpose.” (A, 04:19)
  • Shelby points out that the failed ambitions of these nations serve as reminders that lasting peace and true purpose are found in God, not in systems of human wisdom.

Transcript

[A]

Hey, you're listening to A Year in the Bible with Daily Grace. This is Shelby, and I'm here with Paul. We hope that you'll leave comment or review after watching today's episode. Today we're in Isaiah 16 through 18. Paul, can you give us just an overview of what's happening in these chapters?

[B]

Yeah. Today we continue with the judgments against the nations. And today we're going to read a continuation of the judgment against Moab. Then we're going to have new judgments against Damascus, the northern kingdom of Israel, and which, you know, interestingly, it's kind of treated as a foreign nation here because they had attacked the southern kingdom, the Kushites, and then a reference to all of the nations receiving judgment.

[A]

Okay, well, let's dive a little deeper into today's chapters, and, yeah, we'd love for you to walk us through them.

[B]

Yeah, so I think it's actually a good opportunity here to kind of talk about the relationship between Israel and. And the foreign nations. So we've been tracing through the Old Testament that Israel is God's chosen people, his chosen nation. And he makes these covenants and promises with them that kind of guarantee their relationship. But we also have back in the Abrahamic covenant, this discussion of or this promise that through Abraham, all the nations of the earth will be blessed. And it shows us two things. It shows us, one, that even though God is the God of Israel, he's actually sovereign over all the nations. And second, it shows that Israel is not just in relationship with God for their own sake, but actually for the sake of these nations that are receiving judgment in today's chapters. And so we see a small fulfillment of that promise in the Abrahamic covenant in that foreigners that were living amongst Israel are actually allowed to be included in the covenant. Deuteronomy 10:18 says that God loved the foreigners residing among Israel and gave them food and clothing. But then Leviticus 24:22 declared that you shall have the same rule for the sojourner and for the native, for I am the Lord your God. So essentially what this is saying is that foreigners living amongst Israel, to benefit from the promises and the covenants, had to become Jews. In a sense. They had to follow the law. They had to be circumcised. But through Jesus, everything about that relationship changed. And the apostles even kind of wrestled with this. They kind of. The Book of Acts, we see they're kind of trying to figure out, what does it mean that Gentiles are receiving salvation. And so in Acts 15, they actually decide at the Council of Jerusalem, that they don't. Gentiles don't have to be circumcised. Foreign nations don't have to be circumcised to receive the promise of Jesus. And so this means that we Gentiles, non Jews, are brought into the promise of salvation, the promise of deliverance from this very judgment we read in today's chapters as Gentiles, not as Jews. We don't have to become circumcised. We don't have to follow their law. And so I think just going back to this passage today with that in mind, we have all these harsh judgments against the nations. But remember that one day most of God's people is actually going to be Gentiles. It's going to be made up of the foreign nations. And it's kind of crazy to think that at one point all these nations receiving judgment will be the primary people that God calls his.

[A]

Yeah, that is a very crazy thing to think. Think about. So that's really helpful in reading through these judgments for us to understand. But what do we take away from the chapters we read today? What application do we have for our everyday lives?

[B]

My takeaway is really just that it's such a gift to be counted amongst the people of God. All of these nations were sinful, just like we are sinful. And we could very well have received similar judgments. But through Christ, as I mentioned earlier, we were able to be included in the family of salvation. And so it's just a chance to be grateful that I have a relationship with God, that Jesus broke down the sin that separated me from him. And even as the judgments are harsh, I'm grateful to live on this side of the cross knowing that Jesus received that judgment in our place.

[A]

Yeah, absolutely. I think my takeaway, you know, we've seen judgment on several different nations at this point. And I think what I'm struck by is all these nations had built a system, or they had built a nation that they felt would bring them peace. They were advancing their own mission against the nations around them, the people around them. And yet here we see God judging them. And so I think the folly of human wisdom comes to mind, and just the fact that it is in God alone that we find peace, that we find rest, that we find our true meaning and purpose. And so as we've seen, just all these different nations and God's judgments on them, I'm reminded that all of those are built on human wisdom. And it is God's wisdom alone that he rules the world by which is where we truly find our meaning in our peace and our rest as a person. So, okay, thank you so much, Paul, for walking through these chapters. We're going to keep going through the Book of Isaiah. Lots more great stuff to get through. We'll be back tomorrow.
