READ : Genesis 26:1-6
You are the sons of the prophets and of the covenant that God made with your fathers, saying to Abraham [and Isaac], “And in your offspring shall all the families of the earth be blessed.” (Acts 3:25)
When God first called Abraham, he said to him: “In you all the families of the earth shall be blessed” (Gen. 12:3). As time moved on, God defined that promise further for Abraham when he said about his son Isaac, “In your offspring shall all the nations of the earth be blessed” (22:18). Now in 26:4, after Abraham has died, God repeats the promise to Isaac: “And in your offspring all the nations of the earth shall be blessed.”
You see, when God makes a promise, he doesn’t give up. He continues the march of history until that promise is fulfilled. God remains faithful to his promises—even if we as humans are faithless (see 2 Tim. 2:13).
Be sure to read the entire temple sermon of Peter in Acts 3. Luke only summarizes this message there, but it is clear that Peter first told the story of Jesus’ life, death, and resurrection and then demonstrated how a large number of Old Testament prophecies had been fulfilled by their faithful God—including that core promise to Abraham and Isaac. We serve a God who, when he makes a promise, will not stop until that promise has been brought to fulfillment.
Thank you, dear God, for your faithfulness to your promises. I could not live a day unless I knew that was true. I believe in you. Amen.
