1. The grace of faith, whereby the elect are enabled to believe to the saving of their souls, (Heb. 10:39) is the work of the Spirit of Christ in their hearts, (2 Cor. 4:13, Eph. 1:17–19, Eph. 2:8) and is ordinarily wrought by the ministry of the Word, (Rom. 10:14,17) by which also, and by the administration of the sacraments, and prayer, it is increased and strengthened. (1 Pet. 2:2, Acts 20:32, Rom. 4:11, Luke 17:5, Rom. 1:16–17)
2. By this faith, (a Christian believeth to be true whatsoever is revealed in the Word,) for the authority of God Himself speaking therein; (John 4:42, 1 Thess. 2:13, 1 John 5:10, Acts 24:14) and acteth differently upon that which each particular passage thereof containeth; yielding obedience to the commands, (Rom. 16:26) trembling at the threatenings, (Isa. 66:2) and embracing the promises of God for this life, and that which is to come. (Heb. 11:13, 1 Tim. 4:8) But (the principal acts of saving faith) are accepting, receiving, and resting upon Christ alone for justification, sanctification, and eternal life, by virtue of the covenant of grace. (John 1:12, Acts 16:31, Gal. 2:20, Acts 15:11)
3. This faith is (different in degrees,) weak or strong; (Heb. 5:13–14, Rom. 4:19–20, Matt. 6:30, Matt. 8:10) may be often and many ways assailed, and weakened, but gets the victory: (Luke 22:31–32, Eph. 6:16, 1 John 5:4–5) growing up in many to the attainment of a full assurance, through Christ, (Heb. 6:11–12, Heb. 10:22) who is both the author and finisher of our faith. (Heb. 12:2)
