Stephen spoke on Psalm 23 last night and there was a lady there and she made the comment "When David wrote this it wasn't a timid prayer it was a declaration". why do we so often forget this assurance?

The Lord is my Shepard i shall not want.. when i read this i think well actually YES i have been, still am, and probably will be in want tomorrow, so what is David saying?

your mercy is enough so i shall not be in want
You are eternally faithful so i shall not be in want
You are love so i shall not be in want
Your grace is sufficient so i shall not be in want

it comes down to our trust God provides and sustains... He doesn't just arrive last minuet to save the day he is consistently faithful sometimes we are just to worried with our WANTS to see he hands working.
