John 17:21
King James Version
“That they all may be one; as thou, Father, in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.”
Context
18As thou hast sent me into the world, even so have I also sent them into the world.
19And for their sakes I sanctify myself, that they also might be sanctified through the truth.
20Neither pray I for these alone, but for them also which shall believe on me through their word;
21That they all may be one; as thou, Father, in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
22And the glory which thou gavest me I have given them; that they may be one, even as we are one:
23I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
24Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.
