When you were little, did you ever ask someone to leave the light on? Somehow the warm glow of the hall light made me feel better about the dark. I knew someone was there, watching over me.
You can trust, He will leave the light on for you.
God does not want you wandering around in the wilderness bumping into things! When He led the people of Israel, He promised to be there in the day as a pillar of smoke and in the night as a pillar of fire. He kept his promise to them and He will do the same for you.
