“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 (Ps. 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).
5. Faith will help the soul to wait, though God defers to give; but unbelief will take huff and throw up all, if God makes any tarrying (Psa 25:5; Isa 8:17; 2 Kings 6:33; Psa 106:13, 14).
6. Faith will give comfort in the midst of fears; but unbelief causeth fears in the midst of comfort (2 Chron 20:20, 21; Matt 8:26; Luke 24:26; 27).
7. Faith will suck sweetness out of God’s rod; but unbelief can find no comfort in his greatest mercies (Psa 23:4; Num 21).
8. Faith maketh great burdens light; but unbelief maketh light ones intolerably heavy (2 Cor 4:1; 14–18; Mal 1:12, 13).
9. Faith helpeth us when we are down; but unbelief throws us down when we are up (Micah 7:8–10; Heb 4:11).
10. Faith bringeth us near to God when we are far from him; but unbelief puts us far from God when we are near to him (Heb 10:22; 3:12, 13).
11. Where faith reigns, it declareth men to be the friends of God; but where unbelief reigns, it declareth them to be his enemies (John 3:23; Heb 3:18; Rev 21:8).
12. Faith putteth a man under grace; but unbelief holdeth him under wrath (Rom 3:24–26; 14:6; Eph 2:8; John 3:36; 1 John 5:10; Heb 3:17; Mark 16:16).
13. Faith purifieth the heart; but unbelief keepeth it polluted and impure (Acts 15:9; Titus 1:15, 16).
14. By faith, the righteousness of Christ is imputed to us; but by unbelief, we are shut up under the law to perish (Rom 4:23, 24; 11:32; Gal 3:23).
15. Faith maketh our work acceptable to God through Christ; but whatsoever is of unbelief is sin. For without faith it is impossible to please him (Heb 11:4; Rom 14:23; Heb 6:6).
16. Faith giveth us peace and comfort in our souls; but unbelief worketh trouble and tossings, like the restless waves of the sea (Rom 5:1; James 1:6).
17. Faith maketh us to see preciousness in Christ; but unbelief sees no form, beauty, or comeliness in him (1 Peter 2:7; Isa 53:2, 3).
18. By faith we have our life in Christ’s fullness; but by unbelief we starve and pine away (Gal 2:20).
19. Faith gives us the victory over the law, sin, death, the devil, and all evils; but unbelief layeth us obnoxious to them all (1 John 5:4, 5; Luke 12:46).
20. Faith will show us more excellency in things not seen, than in them that are; but unbelief sees more in things that are seen, than in things that will be hereafter;. (2 Cor 4:18; Heb 11:24–27; 1 Cor 15:32).
21. Faith makes the ways of God pleasant and admirable; but unbelief makes them heavy and hard (Gal 5:6; 1 Cor 12:10, 11; John 6:60; Psa 2:3).
22. By faith Abraham, Isaac, and Jacob possessed the land of promise; but because of unbelief, neither Aaron, nor Moses, nor Miriam could get thither (Heb 11:9; 3:19).
23. By faith the children of Israel passed through the Red Sea; but by unbelief the generality of them perished in the wilderness (Heb 11:29; Jude 5).
24. By faith Gideon did more with three hundred men, and a few empty pitchers, than all the twelve tribes could do, because they believed not God (Judg 7:16–22; Num 14:11, 14).
25. By faith Peter walked on the water; but by unbelief he began to sink (Matt 14:28–30).
Thus might many more be added, which, for brevity’s sake, I omit; beseeching every one that thinketh he hath a soul to save, or be damned, to take heed of unbelief; lest, seeing there is a promise left us of entering into his rest, any of us by unbelief should indeed come short of it.”
