John 14:10-11 NIV

[10] Don’t you believe that I am in the Father, and that the Father is in me? The words I say to you I do not speak on my own authority. Rather, it is the Father, living in me, who is doing his work. [11] Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the works themselves.
