Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God;
Philippians 4:6 (NKJV)
It takes a daily training of the mind to rid ourselves from the unproductive habbit of worry, and instead take our needs and requests to God in simple and childlike faith. Whatever need may arise, let us bring it to God in the full assurance that God before the foundation of time has already made provision for it. Then by faith we receive the supply, the deliverance or the healing that God by His grace has already set before us.
