John 14:12-16

12Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. 13And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. 14If ye shall ask any thing in my name, I will do it.

15If ye love me, keep my commandments. 16And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
