19 Now these are the records of the generations of Isaac, Abraham’s son: Abraham became the father of Isaac;20 and Isaac was forty years old when he took Rebekah, the daughter of Bethuel the Aramean of Paddan-aram, the sister of Laban the Aramean, to be his wife. 21 Isaac prayed to the LORD on behalf of his wife, because she was barren; and the LORD answered him and Rebekah his wife conceived. 22 But the children struggled together within her; and she said, “If it is so, why then am I this way?” So she went to inquire of the LORD. 23 The LORD said to her,
“Two nations are in your womb;
And two peoples will be separated from your body;
And one people shall be stronger than the other;
And the older shall serve the younger.”
24 When her days to be delivered were fulfilled, behold, there were twins in her womb. 25 Now the first came forth red, all over like a hairy garment; and they named him Esau. 26 Afterward his brother came forth with his hand holding on to Esau’s heel, so his name was called 1Jacob; and Isaac was sixty years old when she gave birth to them.
Again, the promise of God to Abraham was in jeopardy. Rebekah was barren, just as her mother-in-law had been. But Isaac knew what God was capable of. He was the son of a woman barren until she was ninety years old. So he prayed to God that his wife might have children, and God answered him. Often, we forget what God has done, and when we see someone in need of prayer, we just look at them and say, “oh, that’s too bad.” We ought to remember what God is capable of (everything), and never forget to pray for someone in need. You never know what God may do.
