Why are kids scared of the "monster in the closet"? Because they don't TRUST that there isn't a monster in the closet. Parents go through the tedious routine of turning on the light, opening the closet, showing their kid the empty closet and that will typically solve the problem ... until the next night when the same kid is scared of the monster in the closet. We fear when we don't trust. When we trust, we should have no fear.
Lord, help me to trust You and not be a child that requires You to show me an empty closet every time I think there is a monster in it.
