John 2:21 (a) In this passage, the body of the Lord JESUS is represented as a temple in which GOD dwells.
Romans 6:6 (b) Here the word is used as though sin itself owned the body as, in fact, it does in some instances. The entire body, from head to foot, is used by some to serve sin.
Romans 12:5 (a) All the Christians bound together by the Holy Spirit are referred to here as forming the body of CHRIST. The believers on earth are called His very body because they are so precious to Him, and because of His utmost care for them. His life indwells all His church.
Ephesians 1:23 (a) The body is used here in the sense that all the members of the body of CHRIST, those who are saved by grace, belong to one another. As the parts of the body belong to one another and are made to serve one another, so each member of the body of CHRIST serves each other member. No part of the body is independent of any of the rest of the body and so it is among true believers.
