Why is self-righteousness dangerous for Christians?

Self-righteousness poses a significant danger to Christians, as it fosters a sense of pride and independence that distances believers from the grace of God. When we begin to rely on our own efforts for salvation, as seen in Ephesians 2:8-9, we risk missing the beauty of Christ’s atonement and the humility that comes with recognizing our total dependence on Him. God despises this attitude because it robs Christ of His glory and detracts from the centrality of grace in our faith. Christians must constantly guard against this inclination, reminding themselves of the truth that all righteousness comes from Christ alone.
