How do we know that believers are called to serve others?

In the life of faith, believers embody Christ's example of ministry. Just as Christ came not to be served but to serve (Mark 10:45), believers are urged to give themselves in service to others. Paul affirms this in his letters, emphasizing that his life's work is aimed at comforting and uplifting others in their faith (2 Corinthians 1:4). The nature of spiritual life includes sharing blessings with others, thus perpetuating the cycle of grace. Serving others is integral to the Christian calling, highlighting the selflessness that characterizes true faith and discipleship.
