Lesson 1 of 4
Salvation by Grace Through Faith
The Problem: All Have Sinned
Before we can understand the gospel of grace, we must understand why grace is necessary. The Bible is devastatingly clear about the human condition: "For all have sinned, and come short of the glory of God" (Romans 3:23). Not some. Not most. All. Every man, woman, and child born of Adam has inherited a sinful nature and has personally transgressed the holy law of God.
Sin is not merely bad behaviour — it is cosmic rebellion against an infinitely holy Creator. Isaiah 64:6 declares, "But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away." Notice that it is not only our sins that are filthy rags, but our righteousnesses — the very best that fallen man can produce is utterly unacceptable before a holy God.
The penalty for sin is death — not merely physical death, but spiritual separation from God for all eternity. Romans 6:23 states, "For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord." Man is bankrupt before God, utterly incapable of paying his debt or earning his way into heaven. This is the backdrop against which the gospel shines in all its glory. Only when we grasp the depth of the problem can we appreciate the magnitude of the solution.
For all have sinned, and come short of the glory of God; Being justified freely by his grace through the redemption that is in Christ Jesus.
Romans 3:23-24
The Solution: Grace Alone Through Faith Alone
The word "grace" in the New Testament is the Greek word charis, and it means unmerited favour — a gift given to those who deserve the opposite. Grace is not God helping those who help themselves. Grace is God saving those who cannot save themselves. Ephesians 2:8-9 states the matter with crystalline clarity: "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
Notice the structure of this declaration. Salvation is by grace — its source is entirely in God's undeserved kindness. It is through faith — the instrument by which we receive it is simple trust in Christ. It is not of yourselves — it originates entirely outside of human effort. It is the gift of God — a gift, by definition, cannot be earned. It is not of works — human effort, religious ritual, moral improvement, and good deeds are explicitly excluded. The final phrase explains why: lest any man should boast. If salvation depended even one percent on human effort, man would have grounds for boasting in heaven — and God will not share His glory with another.
This is the heart of the gospel. Salvation is a free gift, received by faith, apart from any works of the law. The moment a person trusts in the finished work of Jesus Christ — His death, burial, and resurrection (1 Corinthians 15:1-4) — that person is saved, completely and forever. There is nothing to add and nothing to earn. Christ did it all.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.
Ephesians 2:8-9
Not by Works of Righteousness
The Apostle Paul makes this point again and again throughout his epistles because the human heart perpetually reverts to works-based religion. In Titus 3:5, he writes, "Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost." In Romans 4:5, he states, "But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness." In Galatians 2:16, he declares, "Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified."
The repetition is deliberate. Paul understood that the most dangerous heresy in every age is the notion that man can contribute something to his own salvation. Whether it is circumcision (as in Paul's day), baptism, church membership, tithing, keeping the Sabbath, speaking in tongues, or any other religious work — the moment you add anything to faith in Christ, you have departed from the gospel of grace.
Romans 11:6 settles the matter with finality: "And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work." Grace and works are mutually exclusive when it comes to salvation. You cannot mix them. It is one or the other. The Bible says it is grace.
Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.
Titus 3:5
The Danger of Another Gospel
Paul did not treat the corruption of the gospel as a minor theological disagreement. He treated it as the most serious error imaginable. In Galatians 1:8-9, he wrote, "But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed."
The Greek word translated "accursed" is anathema — devoted to destruction, eternally condemned. Paul pronounces this curse not once but twice, and he applies it universally: even if an apostle or an angel were to change the gospel, that messenger would be damned. The gospel is not subject to revision, cultural adaptation, or theological evolution. It is fixed, final, and inviolable.
What was the "other gospel" that provoked this thundering condemnation? The Judaizers in Galatia were teaching that faith in Christ was necessary but not sufficient — that Gentile converts must also be circumcised and keep the law of Moses to be saved (Acts 15:1). They were not denying Christ; they were adding to Christ. And Paul said that adding to the gospel of grace is not a variation of the gospel — it is a perversion of it, a completely different message that saves no one.
Every religious system that requires human works for salvation falls under this same condemnation. Whether the requirement is baptism, confession to a priest, keeping the sacraments, living a good life, or persevering to the end — if it adds anything to faith in Christ's finished work, it is another gospel. The true gospel is gloriously simple: "Believe on the Lord Jesus Christ, and thou shalt be saved" (Acts 16:31).
Abraham: The Pattern of Justification by Faith
To prove that justification by faith is not a New Testament novelty, Paul reaches back to Abraham — the father of the Jewish nation and the most revered figure in the Old Testament. In Romans 4:1-5, Paul asks, "What shall we say then that Abraham our father, as pertaining to the flesh, hath found? For if Abraham were justified by works, he hath whereof to glory; but not before God. For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness."
Abraham was not justified by circumcision — he was declared righteous in Genesis 15:6, fourteen years before circumcision was instituted in Genesis 17. He was not justified by the law — the law would not be given to Moses for another four centuries. He was justified by faith alone. God made a promise, Abraham believed it, and God credited that faith as righteousness.
This is the pattern for every person who has ever been saved, in every dispensation. Old Testament saints looked forward to the coming Redeemer; we look back to the cross. But the means of salvation has always been the same: grace through faith. No one was ever saved by keeping the law. The law was given to reveal sin, not to remedy it (Romans 3:20). It was a schoolmaster to bring us unto Christ (Galatians 3:24), not a ladder to climb into heaven.
Romans 4:5 contains perhaps the most startling statement in all of Scripture: God "justifieth the ungodly." He does not justify the righteous, the reformed, or the religious. He justifies the ungodly — those who have nothing to offer, who come with empty hands and bankrupt souls, trusting not in their own merit but in the merit of Christ alone.
But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
Romans 4:5
What Does It Mean to Believe?
If salvation is by faith alone, then everything hinges on the meaning of faith. Biblical faith is not a vague hope that things will work out. It is not intellectual agreement with a set of doctrines. It is not a feeling of religious devotion. Biblical faith — pistis in Greek — is personal trust in a specific object: the Lord Jesus Christ and His finished work on the cross.
The content of saving faith is defined in 1 Corinthians 15:1-4: "Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved... how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures." The gospel is the death, burial, and resurrection of Jesus Christ. To believe the gospel is to trust that Christ's death paid for your sins in full, that He was buried, and that He rose again bodily on the third day.
Faith is the hand that receives the gift. It is not the gift itself. The power of salvation does not reside in the strength or quality of your faith — it resides in the object of your faith, which is Christ. A weak hand can receive a magnificent gift. A trembling faith laid upon a mighty Saviour is infinitely more effective than supreme self-confidence laid upon self-effort.
This is why the gospel is good news for sinners, not good advice for saints. You do not need to clean yourself up before coming to Christ. You do not need to promise to be better, to stop sinning, or to dedicate your life. You need only to trust Him — to believe that He did what He said He did, and that His sacrifice is sufficient. "He that believeth on the Son hath everlasting life" (John 3:36). Not "will have" someday, not "might have" if he perseveres — hath, right now, the moment he believes.
