John 10:38

10:38 But if I do them, even if you do not believe me, believe the deeds, so that you may come to know and understand that I am in the Father and the Father is in me.”

John 15:4

15:4 Remain in me, and I will remain in you. Just as the branch cannot bear fruit by itself, unless it remains in the vine, so neither can you unless you remain in me.
