For the pagans run after all these things, and your heavenly Father knows that you need them.  But seek first his kingdom and his righteousness, and all these things will be given to you as well.  Therefore do not worry about tomorrow, for tomorrow will worry about itself.  Each day has enough trouble of its own.

Relying on self may work for a short time, but soon we will exhaust ourselves.    Trusting God for our needs, and our hopes, inreases our faith.  When WE do it, it is “control”.  We are controlling rhe circumstances.  When we trust God to do, to provide, to answer – it is putting our lives in the hands of Our Heavenly Father.  What better place is there?
