Genesis 21:1-8 – A Promise Kept

The long-awaited coming of Isaac reminds us of the long-awaited coming of Jesus Christ. God gives Sarah the ability to have a child in old age, and Isaac is born, just as God said, at the exact time God said.

Abraham names the boy Isaac, meaning laughter, and circumcises him just as God commanded. Isaac’s name will remind them of so many things: Abraham’s laughter of joy at hearing God’s promise of a son through Sarah; Sarah’s laughter of doubt and disbelief; and the name looks ahead to Ishmael laughing at Isaac, God’s people being a laughing-stock to the world, and the joy of the promised Messiah who will come through Isaac.

Sarah is filled with joy sent from God. She has waited a long time for this blessing of a child, and she wants all around her to rejoice with her. She is also filled with amazement that in her old age she is able to have a child and to take care of it. God’s blessings always surpass our expectations, and they should fill us with joy and wonder. Who would imagine that God would do so much for those who deserve so little?
