Susan,<quoted text>"Scripture" means writings that are holy or inspired by God. Only the OT fits this, not the Koran or NT. Jesus is not the Messiah, he is the modern day idol of Israel and is prophesied as that in the scriptures. He fulfilled no messianic prophecy but he did try. The Lord is one (Deut. 6:4), God does not have a biological son except for Adam.
But the OT is a forged copy. The Latin Vulgate was written for this very purpose to show Jesus as the Messiah by forging the verses and filling it up with dubious words. OT is avery poor copy of the Jewish Holy Scriptures.
Have you read the Tanakh? If you read it, you will surely find it better than OT, Susan. Trust me!
