What is the relationship between legalism and idolatry?

Legalism is equated with idolatry because it shifts focus from Christ to our own works as a means of acceptance before God. In Galatians, Paul warns that turning to legalistic practices likens one's faith to the idolatrous worship of 'weak and beggarly elements.' This indicates that legalism does not honor Christ and instead attempts to elevate human efforts to the same level as Christ’s finished work. Therefore, it is essential for believers to avoid any notion that seeks to attain righteousness apart from faith in Jesus alone.
