Overview

Justification is received “by faith alone” (ch. 11), so the Confession now defines that faith. Saving faith is the Spirit’s gift, ordinarily wrought by the Word, by which the soul believes God’s truth and — its principal act — receives and rests on Christ alone for salvation. It varies in strength but, however weak, grows to full assurance through Christ its author and finisher.

The Confession, Section by Section

14.1 — The origin and means of faith

The grace of faith, whereby the elect are enabled to believe to the saving of their souls, is the work of the Spirit of Christ in their hearts, and is ordinarily wrought by the ministry of the Word: by which also, and by the administration of the sacraments, and prayer, it is increased and strengthened.

Scripture Proofs (ESV):

“So faith comes from hearing, and hearing through the word of Christ.” (Rom. 10:17, ESV)

“For by grace you have been saved through faith. And this is not your own doing; it is the gift of God.” (Eph. 2:8, ESV)

Further proofs: 2 Cor. 4:13; Eph. 1:17–19; Luke 17:5; 1 Pet. 2:2; Acts 20:32; Rom. 1:16–17.

Exposition: Faith is “the work of the Spirit of Christ,” not a human achievement — consistent with effectual calling (10.2) and justification (11.1). Its ordinary means is “the ministry of the Word”; it is then nourished by Word, sacraments, and prayer. So faith is God’s gift, but a gift He gives through means we are to use diligently.

14.2 — The acts of faith, and its principal act

By this faith, a Christian believeth to be true whatsoever is revealed in the Word, for the authority of God himself speaking therein; and acteth differently upon that which each particular passage thereof containeth; yielding obedience to the commands, trembling at the threatenings, and embracing the promises of God for this life, and that which is to come. 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.

Scripture Proofs (ESV):

“…to all who did receive him, who believed in his name, he gave the right to become children of God.” (John 1:12, ESV)

“Come to me, all who labor and are heavy laden, and I will give you rest.” (Matt. 11:28, ESV)

Further proofs: Acts 16:31; Gal. 2:20; John 6:35; Phil. 3:9; Isa. 66:2; Heb. 11:13.

Exposition: Faith believes “whatsoever is revealed in the Word” because of God’s authority (cf. 1.4) — obeying commands, trembling at threats, embracing promises. But its principal act is personal: “accepting, receiving, and resting upon Christ alone.” Faith is not mere assent to facts (even demons assent, James 2:19); it is the soul leaning its whole weight on Christ for everything. The empty hand that receives is itself God’s gift (11.1).

14.3 — The strength and growth of faith

This faith is different in degrees, weak or strong; may be often and many ways assailed and weakened, but gets the victory: growing up in many to the attainment of a full assurance, through Christ, who is both the author and finisher of our faith.

Scripture Proofs (ESV):

“…looking to Jesus, the founder and perfecter of our faith.” (Heb. 12:2, ESV)

“I believe; help my unbelief!” (Mark 9:24, ESV)

Further proofs: Matt. 6:30; 8:10; Rom. 4:19–20; Eph. 6:16; 1 John 5:4–5; Col. 2:2.

Exposition: Faith comes in “degrees, weak or strong.” It is assailed and may be weakened, “but gets the victory” — because it rests not on its own strength but on Christ, “the author and finisher.” This is enormous comfort: weak faith in a strong Christ saves, for the saving power is in its object, not its intensity. “Help my unbelief” is a believing prayer.

Doctrinal Summary

Saving faith is the gift of the Spirit of Christ, ordinarily wrought by the Word and strengthened by Word, sacraments, and prayer. It believes all that God reveals on His authority, but its principal act is to accept, receive, and rest upon Christ alone for justification, sanctification, and eternal life. It varies in strength and is often assailed, yet always finally overcomes, growing in many to full assurance — because Christ Himself is its author and finisher.

Pastoral & Practical Significance

This chapter rescues anxious believers who measure their faith and find it small. The Confession does not say faith must be strong to save — it says faith “different in degrees, weak or strong” gets the victory, because its power is in Christ its object. A trembling hand that truly rests on Christ holds Him as surely as a steady one. So the question is never “Is my faith strong enough?” but “Am I resting on Christ alone?” When faith feels weak, the remedy is not to look inward and strain, but to look outward to Christ and use the means He gives — Word, sacraments, prayer — through which He strengthens it. And take heart: the One who began your faith will finish it (Heb. 12:2).

For Reflection

• Is my faith mere assent to true facts, or does it “rest upon Christ alone” for everything?
• When my faith feels weak, do I despair of myself or look to Christ “the author and finisher”?
• Am I using the means — Word, sacraments, prayer — by which God ordinarily strengthens faith?
