New Apologetics Book, 25 Reasons to be Christian.

[zebo-the-fat]

Sigh. Ok. We'll go from there. Now, as to how the True God, the Lord Jehovah, is different from many false gods is this God revealed Himself to be One Almighty God, Eternal and Transcendent. The many false pagan gods were not like this and they all believed gods could be multiple, divided, not almighty, not transcendent, not outside time etc. Next, the Kalam Cosmological argument, which Dr. Craig generally starts with, and I agree is a good argument, proves precisely such a God as the monotheistic God defended by just 3 of the world's 10 or so religions: Christianity, Judaism, and Islam. It thus excludes polytheistic gods and polytheistic religions and all those that have not been consistently monotheistic in maintaining the Truth of One Almighty Creator God.

Now, the Kalam is well known: (1) What begins to exist has a cause. (2) But, the Universe began to exist. (3) Thus, there exists a Cause of the Universe that existed outside time and space before the Universe came to being. (4) Next, we can deduce even further Properties of this First Cause, namely that it is (1) Almighty or Omnipotent, because only an Almighty Power can create something out of nothing, let alone whole universes out of nothing. (2) Eternal and Transcendent, i.e. existing outside time and space. And that will do for now.

Note that the properties we deduce are completely in accord with what the Lord Jehovah, the One True God, revealed to the Patriarch Abraham, the founding father of monotheism. They thus answer your second point and show we can in fact exclude various polytheistic false gods from being the True Creator God that the Kalam proves.

How did this god "reveal Himself"?  How is this different from people just making stuff up?
Still waiting for some testable falsifiable evidence.
