Christian will hate the things once loved, and love the things once hated. 

Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God. (1 John 3:9)

I heard a man say once, “Sir, if I believed that doctrine I should live in sin.” My reply to him was this, “I dare say YOU would! I dare say YOU would! “ “And why,” said he, “should I more than you?” Simply because you are a man, and I trust I am a new man in Christ Jesus. To man that is renewed by grace, there is no doctrine that could make him love sin.

 If a man by nature be as a swine that wallows in the mire, turn him into a sheep, and there IS no doctrine you can teach that can make him go and wallow in the mire again. His nature is changed. There is a raven transformed into a dove. I will give the dove to you, and you may teach it whatever you like, but that dove will not eat carrion any mine. It cannot endure it: its nature is entirely changed. Here is a lion roaring for its prey. I will change it into a lamb; and I defy you to make that lamb, by any doctrine, go and redden its lips with blood. It cannot do it — its nature is changed.

A friend on board the steamboat, when we were coming across from Ireland, asked one of the sailors, “Would you like a nigger song?” “No,” said he, “I do not like such things.” “Would you like a dance?” “No,” said he, “I have a religion that allows me to swear and be drunk as often as ever I please, and that is never: for I hate all such things with perfect hatred.” Christian men keep from sin because their nature abhors sin. Do not imagine we are kept back from sin because we are terrified with threats of damnation, we have no fear, except the fear of offending our loving Father But we do not want to sin — our thirst is for holiness and not for vice. But if you have a kind of religion that always keeps you in restraint, so that you say, “I should like to go to the theater to-night if I dare,” — if that is what you say, depend upon it, your religion is not of much value. You must have a religion that makes you hate the thing you once loved, and love that which you once hated — a religion that draws you out of your old life and puts you into a new life.
