I 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.
I in them and you in me, that they may become perfectly one, so that the world may know that you sent me and loved them even as you loved me.
I am in them and you are in me. May they experience such perfect unity that the world will know that you sent me and that you love them as much as you love me.
