Quran 61:6-7
And when said Jesus, the son of Mary: "O children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad." But when he came to them with clear evidences, they said, "This is obvious magic."
John 16:7 / 14:16
It is expedient for you that I go away; for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
And I will pray to the Father, and he shall give you another Comforter, that he may abide with you for ever. (John 14:16)
