Faith is not believing just anything . It is believing God, resting in Him, and trusting His Word. Faith gives birth to prayer. It grows stronger, strikes deeper, and rises high in the struggles and wrestling of mighty petitioning. Faith is the substance of things hoped for, the confidence and reality of the inheritance of the saints.
Faith is the one great condition of prayer.
Doubt and fear are the twin enemies of faith. Sometimes, they actually take the place of faith, and although we pray, it is a restless, disquieted, uneasy, complaining prayer that we offer. Peter failed to walk on Galilee because he allowed the waves to break over him and swamp the power of his faith. Doubts and fears should never be cherished or hidden. Our eyes should be taken off ourselves.
