John 17:22 And the glory which You have given Me I have given to them, that they may be one, even as We are one; (23) I in them, and You in Me, that they may be perfected into one, that the world may know that You have sent Me and have loved them even as You have loved Me.
The Son has been given the Father's life and nature that He may express the Father. The glory of the Son is that He expresses the Father by having the Father's life and nature. Suppose the President has a son whom he sends as his representative.
The glory of this son is that he expresses the President in life and nature. This very glory of the Son He has given to us. We share the Father's life and nature and have the position and right to express Him.
We have this glory! We are brought into oneness, then in this glory. This oneness is genuine because it is in the Triune God.
We are not trying to be one in doctrine or in practices; a oneness in these areas is not genuine. Our oneness is in the Triune God, not in our beliefs or ways of doing things. As those who believe in the Lord Jesus and are the regenerated children of God, we are all members of the Body of Christ.
Regardless of the differences we may have in practice or in doctrine, we have no way but to remain here in the genuine oneness. We can give no place to idol worship, immorality, division, or the denial of Christ's divinity and redemptive work. But of other things we must be tolerant.
May the Lord preserve us in Himself that we may enjoy the real oneness.
