It was to inspire faith in His ability to do that Jesus left behind Him, that last, great statement, which, in the final analysis, is a ringing challenge to faith. Like the man who was born blind, it goes to wash in the pool of Siloam when told to wash. Like Peter on Gennesaret it casts the net where Jesus commands, instantly, without question or doubt. Such faith takes away the stone from the grave of Lazarus promptly. A praying faith keeps the commandments of God and does those things which are well pleasing in His sight.
Obedience helps faith, and faith, in turn, helps obedience.
To do God's will is essential to true faith, and faith is necessary to implicit obedience. Yet faith is called upon, and that right often to wait in patience before God, and is prepared for God's seeming delays in answering prayer. There is bound to be much delay and long days of waiting for true faith, but faith accepts the conditions - knows there will be delays in answering prayer, and regards such delays as times of testing, in the which, it is privileged to show its mettle, and the stern stuff of which it is made. Faith deals with God, and is conscious of God. Faith is not an aimless act of the soul, but a looking to God and a resting upon His promises.
