15 God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. 16 I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.” 17 Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” Genesis 17:15–17
And
18 Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, “So shall your offspring be.” 19 Without weakening in his faith, he faced the fact that his body was as good as dead—since he was about a hundred years old—and that Sarah’s womb was also dead. 20 Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, 21 being fully persuaded that God had power to do what he had promised. Romans 4:18–21
1 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.” [Note: The name Isaac in Hebrew means he laughs or laughter.] Genesis 21:1–7
21 He [God] will yet fill your mouth with laughter and your lips with shouts of joy. Job 8:21

Then it was said among the nations, “The LORD has done great things for them.” 3 The LORD has done great things for us, and we are filled with joy. Psalm 126:1–3
