+ Isaac + 16 August, Old Testament

If any part of Scripture besides the Resurrection clearly indicates that God gets the last laugh, it's got to be the story of the birth of Isaac, the second of the three great patriarchs of Scripture.

After giving new names to Abraham and Sarah, the Lord promised a them a son. At the time, Abraham was 99 and Sarah was 90 (see Genesis 17). When Abraham heard the news, he "fell on his face and laughed and said to himself, 'Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?' (v. 17)"

In response to the laughter and doubting, the Lord said, "Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him. (v. 19)" Isaac means "He Laughs."

To reiterate His point, the Lord allowed Sarah to overhear Him repeat His promise to Abraham at the Oaks of Mamre (see Genesis 18). "So Sarah laughed to herself, saying, 'After I am worn out, and my lord is old, shall I have pleasure?' The Lord said to Abraham, 'Why did Sarah laugh and say, "Shall I indeed bear a child, now that I am old?" Is anything too hard for the Lord? At the appointed time I will return to you about this time next year, and Sarah shall have a son.' But Sarah denied it, saying, 'I did not laugh,' for she was afraid. He said, 'No, but you did laugh.' (vv. 12-15)"

Sure enough, things happened not as Abraham and Sarah may have expected, but as the Lord had planned and promised. When Abraham was 100 years old, Sarah gave birth and "Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac. (21:3)" Sarah likewise revelled in the irony: "God has made laughter for me; everyone who hears will laugh over me. (v. 6)"

When Isaac was a young man, Abraham took him to Mount Moriah. There, Abraham, obeying God's command, prepared to sacrifice his son as a burnt offering. But God intervened, sparing Isaac's life and providing a ram as a substitute offering (22:1-14).

In so doing, God also pointed to the substitutionary sacrifice of His own Son Jesus Christ for the sins of the world. When the author of Hebrews expounded on the faith of Abraham (11:8-19), he made special note of Abraham's belief that, in order to accomplish His purposes, "God was able even to raise [Isaac] from the dead, from which, figuratively speaking, he did receive him back. (v. 19)"

Abraham sent a faithful servant back among their kinfolk in order to find a bride for Isaac. There, the servant found Rebekah, who gladly traveled with this stranger to a new land, where she was given in marriage to Isaac (Genesis 24). They had twin sons, Esau and Jacob (25:19-26).

In his old age, Isaac became weak and blind. Before he died, he desired to give his blessing and the chief inheritance to Esau, his elder and favorite son, even though the Lord had promised Rebekah that their birth order would be reversed in the blessing and Jacob would be the favored son (25:23). However, Rebekah showed her favorite, Jacob, how to deceive his father and gain the blessing for himself (27:1-40). Of course, this resulted in years of bitter family strife, although Jacob and Esau later reconciled (Genesis 33).

Isaac lived to the age of 180 and was buried by his sons in the family burial cave of Machpelah (35:28-29).
