God had promised that He would make them parents of a son through whom a great nation would come into existence.
We now know that nation is Israel, but they didn’t know that. All they knew is that they were old, really old, and that old, really old people don’t make or have babies.
Has God ever done that to you? Has He ever given you a promise that you could not figure out how in the world He would make good on it?
As I was reading this story I was struck by this description of God (Romans 4:17), “[He] brings the dead back to life and [He] brings into existence what didn’t exist before.”
That’s how God makes good on His promises… He restores life! He creates new when the old won’t work! He “brings into existence what didn’t exist before!”
Man that’s good stuff right there!
Don’t sit around wondering how God is going to do what He said He will do! If He said it, He can do it! Live like you believe that!
Live like Abraham, who in the face of physical limitations, social awkwardness, a skeptical spouse, etc. kept believing God! Check this out:
Abraham’s faith did not weaken, even though he knew that he was too old to be a father at the age of one hundred and that Sarah, his wife, had never been able to have children. Abraham never wavered in believing God’s promise. In fact, his faith grew stronger, and in this he brought glory to God. He was absolutely convinced that God was able to do anything he promised. And because of Abraham’s faith, God declared him to be righteous. (Romans 4:19-22 NLT)
If God has promised you something, no matter what, live like you believe it!
