In Christ’s prayer for unity He specifically said, “I pray not for the world, but for them which thou hast given me [out of the world]; for they are thine” (Jn:17:9). Nowhere in Scripture is there any hint that Christians are to “change the world” (which is under God’s judgment) or “meet community needs” as Promise Keepers advocates. We are to call out of this world “a people for his name” (Acts:15:14). Christ’s concern was for His church, “That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us…even as we are one: I in them, and thou in me, that they may be made perfect in one…” (vv 21-23).
Christ’s prayer was answered through the Father and Son indwelling believers by the Holy Spirit. Having become the “children of God by faith in Christ Jesus” (Gal:3:26), we are united in God’s family for eternity. That unity cannot be shared outside that family. And that unity is expressed through adherence in word and deed to God’s Word and truth (Jn:17:6,8,14,17).
Never are we told to make unity, but to “keep the unity of the Spirit” (Eph:4:3) which we already have in Christ. Our lives and the doctrine upon which our lives are founded are to express God’s Word and His truth. Any deviation therefrom denies the unity which is ours in Christ. Those who are not members of Christ’s body through having believed the gospel are not part of this family, and there is no “unity” believers can fabricate to make them so.
