For even the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many.
Mark 10:45
Every believer is made by Christ a servant of God for the purpose of serving God by ministering to people through the local church. Primarily we are to share the gospel and show the love of God so that all might be saved. Secondary to this is the joy of serving the people of God by ministering to them in love.
