The man believes that he is forgiven. What then? He feels gratitude to him who has pardoned him. Feeling gratitude, it is but natural that he should hate that which displeases his Saviour, and should love intensely that which is pleasing to him who saved him, so that faith operates upon the entire nature, and becomes the instrument in the hand of the regenerating Spirit by which all the faculties of the soul are put into the right condition. As a man thinketh in his heart so is he, but his thinkings come out of his believings; if he be put right in his believings, then his understanding will operate upon his affections, and all the other powers of his manhood, and old things will pass away, all things will become new through the wonderful effect of the faith, which is of the operation of God. Faith works by love, and through love it purifies the soul, and the man becomes a new creature. See ye then the wisdom of God? He may choose what way he will, but he chooses a way which at once guards his grace from our felonious boastings, and on the other hand produces in us a holiness which other wise never would have been there.
