Dear Lord, we are dying of prudence. All Saul had left was the stuff of man, and this left him without courage. What's true at sea is also true in our world. Goliath came each day and taunted Israel about how great he was and how he would destroy whoever came against him.

Why the supermarket where we shop has so many vice presidents they have one who's just in charge of grocery bags. Let's phone the store right now. He was not used to doing things with man's help. He was used to doing things with God's help. Having discarded Saul's stuff, David is still willing to go with confidence that God will help him as before, using what he already knew and what was the stuff of a simple shepherd.
