Henceforth we should not serve sin. Romans 6:6
“Christian, what do you have to do with sin? Has it not cost you enough already? Burned child, will you play with fire? When you have already been between the jaws of the lion, will you step into his den a second time? Have you not had enough of the old serpent? Did he not poison all your veins once, and will you play upon the hole of the asp and put your hand on the serpent’s den a second time? Oh, do not be so foolish!
Did sin ever bring you real pleasure? Did you find solid satisfaction in it? If so, go back to your old drudgery and wear the chain again, if it pleases you. But inasmuch as sin never gave you what it promised to bestow, but deluded you with lies, do not be snared a second time by the old fowler. Be free, and let the remembrance of your ancient bondage forbid you to enter the net again!”
