Just as each of us has one body with many members, and these members do not all have the same function, so in Christ we who are many form one body, and each member belongs to all the others. (Romans 12: 4- 5)
Church has diverse functions although it exists as one body. Having every function fully active builds each church to be strong and able to minister various needs of people.
