Every one of us, with all our shades of individuality, is a descendent of a single pair, Adam and Eve. Our Saviour designed us to live in harmony with His prayer that we would be one just as He and His Father are one (John 17:22), and here is the beauty about this oneness – this unity: it does not mean uniformity. Christ and His Father are two distinct persons, held together in perfect unity with the Holy Spirit by the bond of their identity: “God is love” (1 John 4:8).
