Legalism is the attempt to earn right standing with God through rule-keeping. The Galatian heresy added circumcision and Torah observance to faith in Christ as requirements for salvation — prompting Paul's fiercest letter: "If righteousness come by the law, then Christ is dead in vain" (Galatians 2:21). Grace is the opposite: God's free, unmerited favor given to sinners through Christ. "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). But grace does not abolish obedience — it empowers it. "For the grace of God that bringeth salvation hath appeared to all men, teaching us that, denying ungodliness... we should live soberly, righteously" (Titus 2:11-12).
GRACE: The free unmerited love and favor of God. LEGAL: Pertaining to law; according to law.
GRACE, n. [L. gratia.] 1. Favor; good will; kindness. 2. In theology, the free unmerited love and favor of God, the spring and source of all the benefits men receive from him. 3. The application of Christ's righteousness to the sinner. Webster understood grace as entirely unearned — the foundation of salvation, not its reward.

"Legalism" is used to silence all moral standards, while "grace" is used to excuse all sin.
The word "legalism" has become the most abused term in modern Christianity. Any call to obedience, holiness, or moral accountability is dismissed as "legalistic." But calling sin what it is, is not legalism — legalism is trusting in your obedience for salvation. Conversely, "grace" has been distorted into permission to sin. Bonhoeffer called this "cheap grace" — grace without discipleship, cross, or transformation. Biblical grace is costly: it cost Christ His life, and it demands ours. The true relationship between law and grace is not opposition but fulfillment: grace saves us from the penalty of law-breaking and empowers us to keep the law from the heart.
• "Grace does not mean God stopped caring about obedience — it means He gave you the power to obey from a transformed heart."
• "Calling someone 'legalistic' for upholding biblical morality is itself a form of antinomian legalism — enforcing the rule that there are no rules."
• "Legalism says 'obey and God will love you.' Grace says 'God loved you, therefore obey.'"
