Why is humility important for Christians in light of justification?

Humility is vitally important for Christians, particularly in the context of justification, because it recognizes that none of us can earn standing before God through our works. As illustrated in Luke 18, the self-righteous Pharisee failed to attain justification, while the humble publican received it. God opposes the proud but gives grace to the humble (James 4:6), highlighting that understanding our position as sinners in need of grace is pivotal. It is only through humility that we can embrace the truth that justification is not about our achievements but solely about what Christ has accomplished on our behalf.
