As Jesus and the Father are one, so is His desire for all believers

John 17:11 (ASV)

¹¹And I am no more in the world, and these are in the world, and I come to thee. Holy Father, keep them in thy name which thou hast given me, that they may be one, even as we are.

John 17:21–23 (ASV)

²¹that they may all be one; even as thou, Father, art in me, and I in thee, that they also may be in us: that the world may believe that thou didst send me. ²²And the glory which thou hast given me I have given unto them; that they may be one, even as we are one; ²³I in them, and thou in me, that they may be perfected into one; that the world may know that thou didst send me, and lovedst them, even as thou lovedst me.

Romans 15:5–6 (ASV)

⁵Now the God of patience and of comfort grant you to be of the same mind one with another according to Christ Jesus: ⁶that with one accord ye may with one mouth glorify the God and Father of our Lord Jesus Christ.
