Genesis 21:3
“Abraham called his son who was born to him, whom Sarah bore to him, Isaac.”
What does Genesis 21:3 mean?
Abraham names his newborn son Isaac, fulfilling God's promise of a child born to him and Sarah in their old age. The name itself means "he laughs," which connects to Sarah's earlier laughter of disbelief when she first heard she would bear a son, and later her joy at his birth. This simple act of naming marks a profound turning point: the long-awaited heir has finally arrived, and God's covenant promise is beginning to take shape. For Abraham and Sarah, this child represents not just a son, but the concrete evidence that God keeps his word, even when circumstances seem impossible.
