The revelation of the Triune God comes from Jesus, himself.
Jesus said he was God (the Jews were very clear on that point--see my post #96 on Jesus and Claim to Divinity thread).
John said Jesus was God (Jn 1:1-3).
Jesus spoke of the Holy Spirit as a divine person, another Comforter, as the person Jesus was a comforter.
Jesus referred to the Holy Spirit with the personal pronoun "he" (Jn 14:16-17,25-26, 15:26, 16:7).
The New Testament presents three divine persons in one God.
You fail to realise that the prophecy clearly says that only if Jesus (pbuh) departs will the Comforter come.....see the full context.........The Bible states that the Holy Spirit was already present on earth before and during the time of Jesus (pbuh), in the womb of Elizabeth, and again when Jesus (pbuh) was being baptised, etc
second Jesus never said he was God , its clearly mentioned he was Prophet of God
