4. It is that sin, above all others, that most suiteth with the wisdom of our flesh. The wisdom of our flesh thinks it prudent to question awhile, to stand back awhile, to hearken to both sides awhile; and not to be rash, sudden, or unadvised, in too bold a presuming upon Jesus Christ. And this wisdom unbelief falls in with.
5. It is that sin, above all other, that continually is whispering the soul in the ear with mistrusts of the faithfulness of God, in keeping promise to them that come to Jesus Christ for life. It also suggests mistrust about Christ’s willingness to receive it, and save it. And no sin can do this so artificially as unbelief.
6. It is also that sin which is always at hand to enter an objection against this or that promise that by the Spirit of God is brought to our heart to comfort us; and if the poor coming sinner is not aware of it, it will, by some evasion, slight, trick, or cavil, quickly wrest from him the promise again, and he shall have but little benefit of it.
7. It is that, above all other sins, that weakens our prayers, our faith, our love, our diligence, our hope, and expectations: it even taketh the heart away from God in duty.
8. Lastly, This sin, as I have said even now, it appeareth in the soul with so many sweet pretences to safety and security, that it is, as it were, counsel sent from heaven; bidding the soul be wise, wary, considerate, well-advised, and to take heed of too rash a venture upon believing. Be sure, first, that God loves you; take hold of no promise until you are forced by God unto it; neither be you sure of your salvation; doubt it still, though the testimony of the Lord has been often confirmed in you. Live not by faith, but by sense; and when you can neither see nor feel, then fear and mistrust, then doubt and question all. This is the devilish counsel of unbelief, which is so covered over with specious pretences, that the wisest Christian can hardly shake off these reasonings.
[Qualities of unbelief as opposed to faith.]—But to be brief. Let me here give thee, Christian reader, a more particular description of the qualities of unbelief, by opposing faith unto it, in these twenty-five particulars:—
1. Faith believeth the Word of God; but unbelief questioneth the certainty of the same (Psa 106:24).
2. Faith believeth the Word, because it is true; but unbelief doubteth thereof, because it is true (1 Tim 4:3; John 8:45).
3. Faith sees more in a promise of God to help, than in all other things to hinder; but unbelief, notwithstanding God’s promise, saith, How can these things be? (Rom 4:19-21; 2 Kings 7:2; John 3:11,12).
4. Faith will make thee see love in the heart of Christ, when with his mouth he giveth reproofs; but unbelief will imagine wrath in his heart, when with his mouth and Word he saith he loves us (Matt 15:22,28; Num 13; 2 Chron 14:3).
