Why should Christians seek to serve and live for others?

In John 12:25, Jesus makes it clear that those who seek to preserve their life for their sole benefit ultimately lose it. Conversely, those who offer their lives in service to others find true life. This principle is rooted in Christ's example; He demonstrated ultimate service and love by laying down His life for the world. Christians are encouraged to follow His example, embodying selflessness and humility. Serving others provides an avenue for expressing faith and glorifying God, fulfilling the command to love one another as Christ loved us (John 13:34-35). This is the essence of the Christian life—being a blessing to others and contributing to the growth of God’s Kingdom.
