It (prayer) dispels frivolity and drives away all skin-deep forms of worship, and makes worship a serious and deep-seated service, impregnating body, soul, and spirit with its heavenly infusion.
~ E. M. Bounds
Jesus taught that perseverance is the essential element of prayer. Men must be in earnest when they kneel at God's footstool. Too often we get faint-hearted and quit praying at the point when we ought to begin. We let go at the very point where we should hold on strongest. Our prayers are weak because they are not impassioned by an unfailing and resistless will.
