I was reading through my Bible reading yesterday, and I was caught on Deuteronomy 7:17-19. Here God is telling Israel to go in and conquer the land that He is giving them. God tells them that if they feel too small and inadequate, they should not be afraid. They should not. So what are they to do instead of being afraid? They should remember what God has already done.
It reminds me of hard times in the life of an individual. If God is with you and God has told you to go and do, then you really should not be afraid. Just remember what God has already done and know that He can do it again. He can do something else entirely new if He wants to.
If God calls, He makes you ready. Everything is technically already done except for the part where you go and do.
So go and do. Don’t be afraid, but remember well.
