The members of Christ are members of God's family. How do we become members of the divine family? "Except a man _be born again_, he can not see the kingdom of God" (John 3:3). "As many as received him, to them gave he power to become the sons of God ... which were _born ... of God_" (John 1:12, 13). "Beloved, now are we the sons of God" (1 John 3:2). Since this family, or church, is composed of the saved, or those who are born again, and excludes all the unsaved, we can understand Paul's reference to "a glorious church, not having spot, or wrinkle, or any such thing," but "_holy and without blemish_" (Eph. 5:27). We have spoken of the union of all believers with Christ when he draws them unto himself and becomes their spiritual life. But this unity of all believers _with Christ_ is a spiritual relationship and experience not to be confused with external things. The Bible speaks of Christians as being "in Christ." What does this mean? It certainly means to be "born again," for without that experience we "can not see the kingdom of God" (John 3:3). "Therefore if any man be _in Christ_, HE IS A NEW CREATURE: old things are passed away; behold, all things are become new" (2 Cor. 5:17). "Whosoever abideth _in him_ sinneth not: whosoever sinneth hath not seen him, neither known him" (1 John 3:6). [Sidenote: Unity of believers] But our union with Christ, by which we become members of the divine family, necessarily fixes our relationship with all those who are members of Christ. If, through salvation, we are brought into a sacred unity with Christ, we are by the same act brought into essential unity and fellowship with the members of Christ. This the Word distinctly affirms: "We, being many, are one body in Christ, and _every one members one of another_" (Rom. 12: 4, 5). "There should be no schism in the body; but the members should have the same care one for another" (1 Cor. 12:25). While this last text relates literally to the physical body, the apostle applies it in an illustrative way to the spiritual body. "Now ye are the body of Christ, and members in particular" (verse 27). [Sidenote: Unity and uniformity]
