Ministry
"Ministry" is from the Greek word diakoneo, meaning "to serve" or douleuo, meaning "to serve as a slave." In the New Testament, ministry is seen as service to God and to other people in His name. Jesus provided the pattern for Christian ministry—He came, not to receive service, but to give it (see Matthew 20:28; Mark 10:45; John 13:1-17).
Christians minister by meeting people's needs with love and humility on Christ's behalf (see Matthew 20:26; Mark 10:43; John 2:5,9; Acts 6:3; Romans 1:1; Galatians 1:10; Colossians 4:12). Christians minister to others out of their devotion to Christ and their love for others, whether the other people are believers or unbelievers. Ministry to others should be impartial and unconditional, always seeking to help others as Jesus would.
