The self-willed, headstrong man will likely have the toughest time of any. To let his own plan utterly go, and instead fit into a radically different one will shake him up terrifically. But that mighty One within will lovingly woo and move him. And as he yields, and victory comes, he will be delighted to find that the highest act of the strongest will is in yielding to a higher will when found. He will be charmed to discover that the rarest liberty comes only in perfect obedience to perfect law. And so every sort of man who has gotten some moral twist or obliquity in his mental make-up will be straightened out to the normal standard of his Maker, _as he allows Him to take full control_. The fourth fact:--_All this growth and development will be strictly along the groove of the man's natural endowment._ The natural mental bent will not be changed though the moral crooks will be straightened out. Peter's rash, self-assertive twists are corrected, but he remains the same Peter mentally. He does not possess the rare logical powers of Paul, nor the judicial administrative temper of James, before the infilling, and is not endowed with either after that experience. John's intensity which would call down fire to burn up supposed foes is not removed but turned into another channel, and burns itself out in love. Jonathan Edwards retains and develops his marvelous faculty of metaphysical reasoning and uses it to influence men for God. Finney's intensely logical mind is not changed but fired and used in the same direction.
