John 14:10-11, 20

Do you not believe that I am in the Father, and the Father is in Me? The words that I say to you I do not speak on My own initiative, but the Father abiding in Me does His works. Believe Me that I am in the Father and the Father is in Me; otherwise believe because of the works themselves.

In that day you will know that I am in My Father, and you in Me, and I in you.
