John 17:22,23 ... Jesus is talking to the Father God: "The Glory that You gave Me I have given to them, that they may be one just as We are One: I in them and You in Me; that they may be made perfect in one and that the world may know that You have sent Me, and love them as You love Me."
This "oneness" is the perfect unity that's given by God...our unity with Them and with each other. The
physical unity (the coming together of the church doctrines to make them one)... this unity that people
seem to be looking for will NEVER HAPPEN.
He isn't talking about your body or your soul. He's talking about the REAL you which is your spirit being.
Reverend Robert W. & Mary C. Butler
