We have many members in one body, and all members have not the same office [function]: so we, being many, are one body in Christ.
When a person accepts the Lord Jesus Christ as Savior they become a member of His body. And each member, as in our natural bodies, has a different position, a different function, a different gift, and a different job to do. Our hands are not really concerned with what our feet do, but if our feet stumble and we start to fall, our hands reach out and try to break the fall. Although they are different and do different jobs, they work together as a perfect team. So in the body of Christ. All members are equally important to Him, and they should work together as a perfect team.
