I will just let Spurgeon speak:
“This kind of strict caution is not popular these days, but rest assured, dear reader, it is both the safest and happiest way to live. The one who yields a point or two to the world is in fearsome danger; the one who eats the grapes of Sodom will soon drink the wine of Gomorrah. A little crack in the dike in Holland lets in the sea, and the gap opens quickly until an entire province is drowned. Conformity to the world, in any degree, is a trap for the soul, making it more and more liable to larger, presumptuous sins. . . .
. . . the Christian who flirts with sin cannot enjoy a clear conscience. Questionable thoughts and behaviors do not need to be questioned; they are wrong to us. We must not toy with temptations, but flee them with all speed. Better to be mocked as a Puritan than despised as a hypocrite.”
