Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised. 2 Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. 3 Abraham gave the name Isaac to the son Sarah bore him. 4 When his son Isaac was eight days old, Abraham circumcised him, as God commanded him. 5 Abraham was a hundred years old when his son Isaac was born to him.
6 Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.” 7 And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
(Genesis 21:1–7, NIV)
Finally, the promise God made to Abram and his wife Sara (now Abraham and Sarah) had come to pass. This was not just any fulfillment of a promise. This promise set in motion an even greater result, that Abraham would become the father of a great nation.
If you know anything about the Abraham and Sarah story, you know they wrestled with fully believing the promise God made to them. (It really did seem impossible!) Why do you think they struggled with this instead of just taking God at his word? Why do we wrestle with God’s promises?
How do you think it would have felt to be Abraham and see this promise come true, even at 100 years of age?
How have you laughed at the fulfillment of the promises of God in your life?
