Text: Genesis 21:1-34

God's Promise is Fulfilled (Gen. 21:1-7)

• God proves to be true to His Word as Isaac is born to Abraham and Sarah.
• Isaac's name (laughter) is proof of God's grace to Abraham and Sarah.

God's Promise is Preserved (Gen. 21:8-21)

• God sets apart Isaac as the one in whom the promise would be fulfilled.
• God's electing grace and common grace are on display with Isaac and Ishmael.
• Galatians 4:21-31 portrays this event as an allegory and how it applies to the Gospel and our identity in Christ.

God's Promise is Progressing (Gen. 21:22-34)

• Abimelech's treaty with Abraham proves that God's promise of land to Abraham's offspring continues to advance.
• As Abraham plants a tree in Beersheba, he is planting his faith in an everlasting God who keeps His promises.
