"I seek at the beginning to get my heart into such a state that it has no will of its own in regard to a given matter. [Most] of the trouble with people generally is just here. [Most] of the difficulties are overcome when our hearts are ready to do the Lord's will, whatever it may be. When one is truly in this state, it is usually but a little way to the knowledge of what His will is."
