MANY MEMBERS –ONE BODY
4For just as each of us has one body with many members, and these members do not all have the same function, 5so in Christ we, though many, form one body, and each member belongs to all the others.
12:4-5 Paul uses the concept of the human body to teach how Christians should live and work together. Just as the parts of the body function under the direction of the brain, so Christians are to work together under the command and authority of Jesus Christ (see 1 Corinthians 12:12-31; Ephesians 4:1-16). Tyndale. Life Application Study Bible
We are all, BELEIVERS, members of the body of CHRIST, the CHURCH. This verse tell us that not all members are the same. That means that another person may not do the exact same thing that you do, but a long as what each member is doing is in the ways and the will of Christ, then the body benefits as a whole as is should. ON THE WAY HOME WALK WITH JESUS as members of his body, the CHURCH.
