To have complete faith or confidence in something or someone is a rare occurrence in this world.  Complete confidence is the strong foundation on which your relationship with God is built.  It is called faith.  The amazing thing about faith and trust is that the more you communicate with God and allow him to be the head of your life, the more it increases as you witness his works.  There is a God and he cares for you.  Take hold of his power.
