What does it mean to mortify self-centeredness?

Mortification of self-centeredness is a biblical concept that requires believers to actively put to death any inclination towards selfishness and ego. The people in Haggai's time prioritized their own comfort over the worship of God, which serves as a cautionary tale for modern Christians. Romans 12:1 urges believers to present their bodies as living sacrifices, holy and pleasing to God, which exemplifies the rejection of self-centered living. By doing so, Christians align themselves with Christ's call to deny themselves and take up their cross, thus living a life that glorifies God above personal desires.
