Our divines, now-a-days, spend a great deal of time in trying to prove Christianity against those who disbelieve it. I should like to have seen Paul trying that! Elymas the sorcerer withstood him: how did our friend Paul treat him? He said “O, full of all subtlety and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?” That is about the politeness such men ought to have who deny God’s truth. We start with this assumption: we will prove that the Bible is God’s word, but we are not going to prove God’s word. If you do not like to believe it, we will shake hands, and bid you good-by; we will not argue with you. The gospel has gained little by discussion…The truth will win the day. Christianity need not wish for controversy; it is strong enough for it, if it wishes it; but that is not God’s way. God’s direction is, “Preach, teach, dogmatize.” Do not stand disputing; claim a divine mission; tell men that God says it, and there leave it. Say to them, “He that believeth shall be saved, and he that believeth not shall be damned;” and when you have done that, you have done enough.

O, Christian, instead of disputing, let me tell thee how to prove your religion. Live it out! live it out! Give the external as well as the internal evidence; give the external evidence of your own life. ~ C.H. Spurgeon
