The fact is that conscience, although it must be to man practically his guide, is not ever a safe one, for the true guide of every man is the Bible, the revealed will of God. That is true, pure and right, but my conscience may often be a dark conscience, an ignorant conscience, a perverted conscience—and so my business is not to follow my conscience as I find it, but to go to God and ask Him to enlighten my conscience and guide it!
Charles H. Spurgeon
