The point of being the church is to magnify His love nature - the purpose of the church is not primarily missions, or even worship, but edification. The people making up an ecclesia gather together to edify one another and "grow in grace" [2 Pet. 3:18], "building one another up until we attain to the unity of the faith and the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ" [Eph. 4:12-14].

This is the nature of Christian interdependence. This is unified oneness, and it is that which Jesus alludes to in his mystical prayer [Jn 17].
