A man may know a great deal about true religion, and yet be a total stranger to it. He may know that Jesus Christ is the Son of God, and yet he may be possessed of a devil. Mere knowledge does nothing for us but puff us up. We may know, and know, and know, and so increase our responsibility, without bringing us at all into a state of salvation.
Beware of resting in head-knowledge. Beware of relying upon orthodoxy, for without love to Christ, with all your correctness of doctrine, you will be a sounding brass and a tinkling cymbal.
It is well to be sound in the faith, but the soundness must be in the heart as well as in the head. There is as ready a way to destruction by the road of orthodoxy as by the paths of heterodoxy. Hell has thousands in it who were never heretics. Remember that the devils "believe and tremble."
There are no sounder theologians than devils, and yet their conduct is not affected by what they believe, and consequently they still remain at enmity to the Most High God. A mere head-believer is on a par therefore with fallen angels, and he will have his portion with them forever unless grace shall change his heart. by C.H. Spurgeon
