John 5:19–20 

 So Jesus explained, “I tell you the truth, the Son can do nothing by himself. He does only what he sees the Father doing. Whatever the Father does, the Son also does. ²⁰ For the Father loves the Son and shows him everything he is doing. In fact, the Father will show him how to do even greater works than healing this man. Then you will truly be astonished.

John 15:4–5 

Remain in me, and I will remain in you. For a branch cannot produce fruit if it is severed from the vine, and you cannot be fruitful unless you remain in me.

⁵ “Yes, I am the vine; you are the branches. Those who remain in me, and I in them, will produce much fruit. For apart from me you can do nothing.
