Many Christians today are living in cycles of shame, confusion, doubt, and fear because they have unknowingly embraced the greatest deception currently poisoning the church. This pervasive lie, which Paul the Apostle severely warned against, is the false gospel of works, also known as legalism.

Understanding the severity and subtlety of this deception is crucial for experiencing the true freedom and peace that Christ intended for believers.

The Urgent Warning Against the False Gospel

The Apostle Paul addressed this dangerous distortion of truth in his letter to the Galatians, expressing shock that they were so quickly turning away from God’s loving mercy.

Paul issued a severe warning, stating that God’s curse should fall on anyone, even an angel from heaven, who preaches a gospel different from the one they originally received. This emphasis highlights that not all deceptions are equally dangerous; a false gospel warrants the highest condemnation because it deliberately twists the truth concerning Christ.

Paul defined this false teaching, asking the Galatians:

• “Oh foolish Galatians, who has bewitched you?”.
• Did you receive the Holy Spirit by obeying the law of Moses, or because you believed the message about Christ?.
• After starting your new lives in the Spirit, why are you now trying to become perfect by your own human effort?.

This deception, which keeps Christians confused about their identity in Christ and what God thinks of them, is legalism.

Defining Legalism: The Gospel of Works

Legalism is not just an insult thrown during a Christian disagreement; it is a profound spiritual error. To be legalistic is to attempt to do in your strength what can only be accomplished in God’s power. This is precisely the gospel of works.

Paul warns that this false teaching, even in small amounts, acts like leaven (yeast) that spreads to the whole batch of dough. Because of human nature, legalism constantly seeks to creep back into the mind, attempting to take root and choke out your joy and peace. If believers are unaware of its presence, the deception can become destructive and torturous.

The Cross vs. Self-Righteousness

The message of the true gospel—the gospel of grace—is often persecuted by the religious system throughout history. The self-righteous are offended by the preaching of the cross because the cross reveals that every person is helpless to save themselves.

Those driven by legalism want to take credit for their good works, earn “points,” and believe they can, on some level, earn their salvation. Grace, however, strikes at the ego of the religious mind.

Grace is Not a License to Sin

It is essential to clarify that the gospel of grace, as preached by Paul, is not a sin-permitting gospel or a distortion of grace. True, godly grace, by its very nature, is extreme, but it does not permit sin.

Instead, grace empowers you unto holiness. Grace is the power required to live as you ought, to recognize your new identity in Christ, and to be in the position where Christ wants you to be.

Subtle Manifestations of the Gospel of Works

The gospel of works is subtle and spreads quickly. It can manifest in the Christian life in several unexpected ways:

1. Equating Harshness with Truthfulness: Some believe a preacher is “not telling the truth” unless he is harsh, mean, or makes them feel bad. This leads to the celebration of “mean-spirited preaching” and the equating of rudeness with truthfulness.
2. Believing Misery is Holiness: The deceptive idea that you must intentionally be miserable or give up enjoyment to “carry your cross”. Carrying the cross simply means doing God’s will despite what you want to do. Sacrificing things God did not ask for (such as a happy, godly relationship or a good-paying job) just for the sake of feeling sacrificial is considered foolishness—a form of self-punishment that subtly attempts to justify wrongdoing (self-righteousness).
3. Self-Hatred Disguised as Humility: When a believer engages in self-hatred, calling themselves a “worm in the ground” or saying they “don’t even deserve to exist,” this is not true humility but rather an attempt at saving oneself. Paul reminds believers of their true identity: they are the righteousness of God in Christ Jesus, children of light, and God’s beloved, having union with God and seated in heavenly places with Christ.
4. Guesswork of Salvation (Trusting Timing over the Cross): Legalism forces Christians to rely on the quality of their current behavior rather than the finished work of Christ. A Christian trapped in this cycle may believe that if they prayed and read their Bible well on Monday, they are saved, but if they rushed out without reading the word on Wednesday, they are “done”. This shows that many Christians do not trust the cross; they trust the good timing of their good deeds.
5. Works as a Burden: Under legalism, spiritual activities like evangelism and church attendance become a burden rather than an expression of joyful worship.

The Assurance of Salvation: Faith is the Root, Works are the Fruit

Legalism causes a Christian to live in constant doubt, fear, and tension, always second-guessing their position with God. The truth of the Gospel corrects this distorted view:

Salvation by Grace, Not Works

Salvation is a gift from God received by grace through belief; it is not a reward for good things done, so no one can boast about it. It is by believing in the heart that a person is made right with God.

Paul emphasizes that those who trust in the law for justification find that Christ has become “of no effect” to them; they have fallen from grace.

Works are the Fruit, Not the Root

The picture often held by Christians is that good works are the roots of the tree of salvation, and these works ultimately produce the fruit of salvation. This is backward.

• The Root of salvation is faith.
• Faith produces the Tree of Salvation.
• The Tree brings forth the Fruit of good works.

Believers do good works because they are saved, not in order to be saved or continue to be saved. Good works are an expression of thanks back to God.

Justification, Sanctification, and Glorification

The Christian life can be pictured as moving through doors and a long hallway:

1. Justification (The First Door): This is a legal term defining your secure position and freedom from the penalty of sin.
2. Sanctification (The Long Hallway): This is the process by which you become more like Jesus, finding freedom from the power of sin. As long as you are in the hallway, you are past the door (justified) and in the process of becoming like Him, even if you sometimes take little steps or stumble.
3. Glorification (The Final Door): This is the final promise where you are forever free from the presence of sin.
