Arise, O God, defend your cause;
remember how the foolish scoff at you all the day!
The mormon god is not the Biblical God,
Mormonism worships an unbiblical God
Joseph Smith was not a prophet of the Biblical God
Do you know what the law of non-contradiction is? If something is true, that which opposes it is false!
In Exodus 3:14, God, Himself is speaking and uses the Hebrew Imperfect grammar to describe Himself to Moses that what He is, He has always been, and the same is used in the Greek grammar to describe Jesus in John 1:1
Joseph Smith in the King Follett Discourse (given on General Conference) taught that God was once a man, just as we are, and that he became a God, and that you have to learn how to become gods
Right there, with that one sentence, Joseph Smith reveals that Mormons do not worship the God of Exodus 3:14, and that he, Joseph Smith was not a prophet of the Biblical God of Exodus 3:14!
The mormon definition and doctrine of god comes 3000 years after Moses wrote Exodus, from Joseph Smith in the King Follett discourse and is contradictory. (You want to claim that the KFD is not central to your doctrine? Your prophet stated this at General Conference, and it is core doctrine!)
Mormons who argue that their beliefs should be accepted as truth do so by rejecting true truth from the discussion, case in point!
