What does the Bible say about humility in Christianity?

In Titus 3:3, the Apostle Paul reminds us of our former state before we received grace: 'For we ourselves also were sometimes foolish, disobedient, deceived...' This acknowledgment of our past serves to cultivate humility in our hearts. Understanding that we, too, were once lost and in error should prevent us from looking down on others who are still in that state. It is by God's grace that we have been changed, and realizing this truth fosters a humble spirit in us, echoing Paul's sentiments that 'by the grace of God I am what I am' (1 Corinthians 15:10). Humility in Christianity is not merely about thinking less of oneself but about recognizing the sovereign grace of God that sets us apart from others.
