The NWT translates Jn 1:1 as "... and the Word was WITH God, and the word was a god." How can the Word (Jesus) be "a god' if God says in Deut 32:39, "See now that I -- I am he, and there are NO gods together with me..."?
Jehovah is called the God of gods, so obviously there are other gods. Jehovah, though, is called the only true God; and those words came straight from the mouth of Jesus. Jesus ought to know.
As regards the statement that there are no gods with him, the Word was with him. Jehovah was stating that the gods of the nations were not with him. The coming of Christ was a sacred secret and the identity of the Messiah was not revealed until after Jesus was baptized. Then it was revealed that Jesus was the son of Jehovah and was the firstborn of all creation, the one to whom Jehovah spoke to during creation, saying: "Let us make man in our image." Obviously, someone was with God.
