The issue of God and gods comes up with the JWs leaders stance of Jesus as a god.

"In Genesis chapter one, God is put in the singular context. He is unambig-
uously singular, and therefore Genesis chapter one could be said to be a Mono-
theistic. (Gen 1:1) However, if we look at God’s interaction with Abraham, the
evidence is less compelling. According to the book of Judith, the Patriarchs
(starting with Abraham), left the gods of their fathers. (Jdt 5:7) God is later
to reveal Himself not as the only God, but rather as the god whom Abraham knows.
(Gen 15:17) In such a respect, God is not God alone, but the god who was wor-
shipped by Abraham’s clan. In such a context, it is a type of tribal deity,
that although was worshipped alone, did not explicitly exclude the existence of
other gods, who were not relevant to them.
"In the early Mosaic era, the possibility of other gods is left an open ques-
tion, although by this stage Israel claims that their God is greater. (Ex 18:11)
This same subtle shift is shown in 2 Chr 2:5, and could indicate that Israel un-
derstood that the God they recognized was God alone, and other gods were there-
fore false. This would be Monotheism in the proper sense of the word. By the
time of the prophet Isaiah, Monotheism is solidly and explicitly accepted.
'Thus says the LORD, the King of Israel and his Redeemer, the LORD of hosts: "I
am the first and I am the last; besides me there is no god.' (Is 44:6) Thus,
the development of the people of Israel to a true Monotheism, appears to be a
gradual process, with the exception of Gen 1:1. It is therefore likely that
Gen 1:1 was redacted later than the other examples supplied, and so, the devel-
opment of Monotheism comes firstly on a tribal level, and gradually advances to
recognition that the God of Israel is the only God. It is into this context
that Christianity emerges, and thus Christianity was from the outset Monotheis-
tic. (John 1:1)"
