And all things are of God, who hath reconciled us to Himself by Jesus Christ… – 2 Corinthians 5:18

We have all heard of the expulsive power of a new affection; this new affection of love to God coming into the soul, expels love to sin. It enters into the heart of man with such a royal majesty about it that it puts down all his predispositions towards evil, and his prejudices against the Most High, and with a real and divine power it reigns within the soul. I suppose the mode of this great change is somewhat after this sort: The man at first is ignorant of his God; he does not know God to be so loving, so kind, so good as he is; therefore the Holy Spirit shows the man Christ, lets him see the love of God in the person of Christ, and thus illuminates the understanding. Whereas the sinner thought nothing of’ God before, or his few stray thoughts were all dark and terrible, now he learns the infinite love of God in the person of Christ, and his understanding gets clearer views of God than it ever had before. Then, in turn, the understanding acts upon the affections. Learning God to be thus good and kind, the heart, which was hard towards God, is softened, and the man loves the gracious Father who gave Jesus to redeem him from his sins. The affections being changed, the whole man is on the way towards a great and radical renewal, for now the emotions find another ruler. The passions, once rabid as vultures at the sight of the carrion of sin, now turn with loathing from iniquity, and are only stirred by holy principle. The convert groweth vehement against evil, as vehement as he once was against the right. Now he longeth and pineth after communion with God as once he longed and pined after sin.

See then, beloved friends, how great is the change wrought in us by our being in Christ! It is a thorough and entire change, affecting all the parts, powers, and passions of our manhood. Grace doth not reform us, but re-creates us; it doth not pare away here and there an evil excrescence, but it implants a holy and divine principle which goes to instant war with all indwelling sin, and continues to fight until corruption is subdued, and holiness is enthroned.~ C.H. Spurgeon
