God made Abraham and Sarah wait more than 25 years for the son He promised—and Paul later reveals why, showing that Hagar and Sarah, Ishmael and Isaac, were a hidden picture of two covenants: law and grace, slavery and freedom. In this study, we'll walk through Genesis 21:1–21 and Galatians 4:21–5:1 and show why God waited until no explanation remained but Himself, and why salvation is a gift you cannot help pay for.

SMALL GROUP QUESTIONS:

- Read Romans 4:18–21 (about Abraham). Abraham's faith grew as he rehearsed what God had actually said. Share a specific promise from Scripture you've leaned on in a hard season.

- Read Hebrews 11:8–13 and 11:39–40. Abraham received Isaac. Many others in that same chapter died still waiting. How do we speak honestly to someone who has waited years and never received the thing? What does faith look like when the answer is "No," or "Not in your lifetime"?

- Read Acts 15:1–11. Peter calls the Law a yoke no one has ever been able to carry—the same argument Paul makes in Galatians 4. Why do you think a "faith plus something" message is so attractive to religious people? What was the appeal of the Judaizers' teaching, and where do you hear a version of it today?

- Read Philippians 3:4–11. What are some things that you used to find your identity and worth in (or still do)? How did Christ work in you to find your identity in Him instead (or how IS He working in you currently)?
