My name is not Paul.
Deut 6:4 "Hear, O Isreal: The LORD our God is one LORD."
1 Kings 8:60 "That all the people of the Earth know that the LORD is God, and that there is none else."
Isa 44:6 "Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God."
Mark 12:29 "And Jesus answered him, The first of all the commandments is, Hear O Isreal; The Lord our God is one Lord."
I'd say those are rather clear. Again, what "Prophet" has told you that what God himself told us, is wrong?
