God's body has the same function as your body; it carries you where you want to go. His "called out" are called to reveal God; so the world can "see" Him, and understand His ways. Without purpose "the church" would be just another group of people, who compare ourselves by ourselves. Our purpose is to show the world God, as He really is [He really does love you]. Local church government not founded with this foundational truth will always find itself in competition with God instead of in cooperation with Him.
If you think you're part of His church, it really boils down to one thing; have you taken His name in vain? If you're a leader in His church this topic is an apostolic truth that does not waiver.
