John 14:10-11

14:10 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 residing in me performs his miraculous deeds. 14:11 Believe me that I am in the Father, and the Father is in me, but if you do not believe me, believe because of the miraculous deeds themselves.

John 14:20

14:20 You will know at that time that I am in my Father and you are in me and I am in you.
