Adults have a way of making things too complex, too difficult, too impossible. That isn't pleasing to the Lord at all. He wants us to trust Him, believe Him, and obey Him.
There is a pureness in childlike faith that touches God's heart. Children come to God accepting Him for who He is and what He has said.
Oh, that God would make me know Him, trust Him, believe Him as a child again. Just to know He is and He will do what He says.
I believe. I know. I accept Him. He is real.
