After twenty-five years of waiting, Abraham and Sarah finally got what God had promised-a baby born to them in their old age. Abraham was 100 and Sarah was 90 when Isaac was born! God waited until they were past their prime so that everyone would know the birth of Isaac was a supernatural event. But then God tested Abraham by asking him to sacrifice his son, Isaac. And just when Abraham was about to carry through with this obedient act, God provided a ram as a substitutionary sacrifice. Find out in today's study how Isaac is a picture of Jesus Christ in the Old Testament as Pastor Gary teaches on "A Sacrifice of Love."
