A frequent misinterpretation is to view this verse as dismissing the law entirely or promoting lawlessness (antinomianism), suggesting faith negates any need for moral conduct; in reality, Paul distinguishes justification (a declarative act by faith alone) from sanctification (ongoing righteous living empowered by that faith), with the law still convicting of sin and instructing believers without justifying them.
Galatians 3:11
King James Version (1769)
11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
Paul emphasizes that justification before God cannot be achieved through obedience to the law, as no one can perfectly fulfill it; instead, drawing from Habakkuk 2:4, he teaches the core gospel truth that the righteous live by faith, meaning trust in God's promise and Christ's redemptive work, which declares believers righteous apart from their merits and empowers a life of faithful obedience.
