I Chronicles 27:23 But David took not the number of them from twenty years old and under: because the LORD had said he would increase Israel like to the stars of the heavens.
God didn’t want His people counting themselves. They counted to see how strong they were. He wanted them to know that their strength came from Him. He won most of their battles with miracles. He gave them the strength to win.
We can never count things like normal men do. We have a God that we can count on. He will do more than we ever could. He will make us more than we are.
