Abimelech and Sarah
GOD always keeps His Word and fulfills His promise in a most wonderful and remarkable way. What He did for Sarah He also did for Abraham. We remind you again that the Bible says, “Abraham was old and well-stricken in years” before God began to work on him. Hebrews tells us that he was as good as dead. Then the Lord sets the clock back for Abraham also, and makes him a young man again. Isaac is born and grows up to manhood. As near as we can reckon, some forty years pass by, during which Sarah dies. And then comes the amazing record of Abraham at the age of about 140 years:
“Abraham took another wife, whose name was Keturah. She bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah” (Genesis 25:1-2).
An amazing record, indeed. Abraham becomes the father of a host of children, six sons are mentioned alone, and how many daughters there were is not mentioned. Abraham, an old man, his body dead, is restored to youth according to God’s promise; and forty years afterwards we have this evidence that when God begins a work, He finishes it. He fulfills His promise that Abraham would not only be the father of the one covenant nation Israel, through Isaac, but also the father of many nations. All of this happens because Abraham believed what God said concerning a long-awaited, supernaturally given, miraculously born child.
I suggest you read the rest of the record of Abraham which tells of his growth in faith, until it reaches a climax in Genesis 22 where he offers his only son upon the altar on Mt. Moriah.
