C. H. Spurgeon
The course of rebellion against God may be very gradual, but it increases in rapidity as you progress in it; and if you begin to run down the hill, the ever-increasing impetus will send you down faster and faster to destruction. You Christians ought to watch against the beginning of worldly conformity. I do believe that the growth of worldliness is like strife, which is as the letting out of water. Once you begin, there is no knowing where you will stop.
I sometimes get this question put to me, concerning certain worldly amusements, "May I do so-and-so?" I am very sorry whenever anyone asks me that question, because it shows that there is something wrong, or it would not be raised at all. If a person's conscience lets him say, "Well, I can go to A," he will very soon go on to B, C, D, E, and through all the letters of the alphabet
When Satan cannot catch us with a big sin, he will try a little one. It does not matter to him as long as he catches his fish, what bait he uses. Beware of the beginning of evil, for many, who bade fair to go right, have turned aside and perished amongst the dark mountains in the wide field of sin.
