The chief cause of slighting Christ and salvation, is a secret root of unbelief.  Whatsoever men may pretend, they do not really believe the Word of God.  They are taught in general to say, the Gospel is true; but they never saw the evidence of its truth, so as to be firmly persuaded of it; nor have they got their souls settled on the infallibility of God’s testimony; no have they considered the truth of particular doctrines revealed in Scripture.

Richard Baxter
