A frequent misinterpretation of this passage is to conclude that good works are entirely irrelevant or prohibited in the Christian life, promoting antinomianism or lawlessness, whereas Paul addresses justification and election specifically, not the ongoing sanctification where believers are indeed called to good works as fruit of genuine faith; another error is to use it to deny any human response to grace, overlooking the biblical balance that faith, empowered by grace, naturally produces obedience.
Romans 11:6
King James Version (1769)
6 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.
Paul emphatically distinguishes grace from works in the context of God's election of Israel, asserting that if salvation or divine favor is by grace, it cannot be based on human works, as the two are fundamentally incompatible; grace is God's unmerited favor, while works imply merit earned by effort, ensuring that God's choice rests solely on His sovereign mercy rather than human achievement.
