'United' in the Bible

Remain in Me, and I [will remain] in you. Just as no branch can bear fruit by itself without remaining in the vine, neither can you [bear fruit, producing evidence of your faith] unless you remain in Me.

If you remain in Me and My words remain in you [that is, if we are vitally united and My message lives in your heart], ask whatever you wish and it will be done for you.

I in them and You in Me, that they may be perfected and completed into one, so that the world may know [without any doubt] that You sent Me, and [that You] have loved them, just as You have loved Me.
