What do we believe about saving faith?

14:1 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; 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 (Luke 17:5; Acts 20:32; Rom 1:16, 17; 4:11; 1 Pet 2:2).

14:2 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; Acts 24:14; 1 Thes 2:13; 1 John 5:10); 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 (1 Tim 4:8; Heb 11:13). 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 15:11; 16:31; Gal 2:20).

14:3 This faith is different in degrees, weak or strong (Matt 6:30; 8:10; Rom 4:19, 20; Heb 5:13, 14); 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 (Col 2:2; Heb 6:11, 12; 10:22), who is both the author and finisher of our faith (Heb 12:2).
