I believe what is in the Great Isaiah Scroll, you are the one under the false assumption that the personal spirit of God and his Salvation exist BESIDES God. The prophecies of the Messiah are contained in the Great Isaiah Scroll, and refer to the nature of the Messiah and the mission (that is completely absent in the koran). The scroll contains the tetragrammaton in ancient Hebrew script (proving the Name wasn't corrupted for the sole purpose of proving mohammed was a false prophet). The scroll also makes it clear that the Spirit of God is a PERSONAL (own) Spirit:<quoted text>
If you believe in what Isaiah wrote then do not believe in the fictitious characters, known as God the Father, God the Son and God the Holy Ghost, who do not exist besides the LORD God Almighty.
Isaiah and other prophets were sent ONLY to the House of Israel. Muhammad was not sent to the House of Israel. He was not an Israelite.
After reading your post, I must say that God the Father, God the Son and God the Holy Ghost look like three stooges to me.
Isaiah (Chapter 30:1) Woe to the rebelling children says YHWH for making counsel but not from me and for covering with a cover but not of my Spirit for the purpose of adding sin to sin.
(40:13.) Who measured out the Spirit of YHWH or what man being his counsellor brought him knowledge.(14.) And who was His counsellor, or who brought Him understanding, or taught him in the path of judgment, or taught him knowledge, and the way of understanding caused Him to know.
(40:3.) A voice crying in the wilderness, Prepare the way of the YHWH, make straight in the desert a highway for our God.
which was claimed to be fulfilled here:
He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias. John 1:23.
Announcing the coming of the 'Word'(aka Messiah/Salvation & called the 'Son').
