Now the LORD was gracious to Sarah as he had said, and the LORD did for Sarah what he had promised. Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. Abraham gave the name Isaac to the son Sarah bore him. When his son Isaac was eight days old, Abraham circumcised him, as God commanded him. Abraham was a hundred years old when his son Isaac was born to him. Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.” 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.”
God Always Keeps His Promises
What an incredible event! A son was born to Sarah when she was well past child-bearing age. Just as he had done with his son Ishmael, Abraham circumcised his son Isaac, setting him apart from other people as a member of the covenant God had made with Abraham.
Sarah’s laughter is pure joy. And she understands Isaac’s name, which means “laughter.” “Who would have thought?” Sarah muses to herself, in awe of God’s grace, power, and faithfulness.
God is faithful; he always keeps his promises—even if they are too incredible for us to understand. He fulfilled his Word of sending his own Son to pay for our sins, and he has promised that on the Last Day, he will raise the dead and take his believers to live with him forever in heaven. We have a gracious, powerful, and faithful God. He will fulfill his promises. He always does.
Faithful God, forgive me when I fail to trust you in all things. Strengthen my hope and confidence through your Word which will never fail. Amen.
