Verily, 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 the Father. And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask anything in my name, that will I do.
Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
