What does the Bible say about pride and self-righteousness?

In Luke 14, our Lord illustrates the dangers of pride and self-righteousness through a parable. He emphasizes that those who exalt themselves will be humbled, while those who humble themselves will be exalted. This reflects the truth that self-righteousness leads to spiritual death, as it falsely elevates one's own works above the need for Christ's grace. As sinners, we must recognize our complete inability to earn favor with God and come to Him in humility, acknowledging our need for His healing grace.
