Spurgeon, "Plain Words with the Careless"
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 by a devil;
no, he may be a den for a whole legion of devils.
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 mere orthodoxy, for without
love to Jesus, 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 theological believers 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.
