Amen, amen, I say to you, whoever believes in me will do the works that I do, and will do greater ones than these, because I am going to the Father. And whatever you ask in my name, I will do, so that the Father may be glorified in the Son.  If you ask anything of me in my name, I will do it.

If you love me, you will keep my commandments.  And I will ask the Father, and he will give you another Advocate to be with you always, the Spirit of truth, which the world cannot accept, because it neither sees nor knows it. But you know it, because it remains with you, and will be in you.

John 14:12-17
