He appointed his disciples to be apostles, evangelists, pastors and teachers in order to help in Christian service and to build up the body of Christ.
The body of Christ can be like these: (1 Co 12:27). (1) One unit (2) Jesus the head (3) working of holy spirit (4) working simultaneously of different organs (5) growth and strength (6) acquiring talents from birth and from the Holy Spirit. Our skills are different. Some can do 2-3 things out of 24 things recorded in the Bible which can be classified into 6 groups. They are knowledge, supporting, evangelizing, do the miracles, administrations and serving.
