Paul uses the illustration of the body to explain the importance of each of us to the healthy functioning of the Body of Christ - His Church. Every one of us is gifted in some way by God to be used in the church. While we may perceive ourselves as inconsequential because of our place in the body, the truth is, no one is an appendix. Every one of us that claim Jesus as our Savior is important to the proper functioning of the church. From the toes to the head, however God has gifted us, we need one another to fully reflect God in Christ to the world.
