From the time we are born we find our identity in contrast to others. The world is divided by family lines, race lines, cultural lines, gender lines, and, yes, even denominational lines. Is Christ divided? Does Christ’s gospel have the power to tear down the partitions between us and other? Remember that when Christ came into the family of Abraham, 2000 years ago, He invited the whole world into Abraham’s family! Can anything contain God without bursting?
If you were to put end to end all of the “one another” texts in the New Testament you would be amazed at God’s vision for His church. How do Christians treat each other? Jesus said that the world would know that we are Christian by the way we treat each other. The world is watching us to see if Jesus has the power to change us. If we put on a show they will know, because only a genuine right relationship with God and to each other can and will expose us to the benefits of the Spirit and relate to the world the love of God.
