Abraham was a hundred years old when his son Isaac was born to him.
After 25 years of waiting, trusting, doubting, remembering - it happens! If God says it, he does it. The laugh of 'that could never happen' has been transformed into the laugh of 'I can't believe this has happened'!
God's character does not change. As he was relentlessly faithful to Abraham, so he is relentlessly faithful to you and me. 25 years is a long time to me, but God is working on a timeline that extends into eternity. The waiting is where I often grow the most.
When I am waiting, I can stand on the solid rock of God's faithfulness. That has never, and will never change.
