What can you predict with the existence of your God that you can't predict without?
The existence of an afterlife. The presence of free will.
And what makes your God more likely than any other God or Gods?
I start with the question, "Is there a God?", by which I mean a being both omnipotent and omniscient. I am confident that the answer to that question is "yes".
I have since assigned a number of further ideas to this concept, some of which are almost certainly wrong (but I'm not sure which ones). It is highly likely that someone else has come up with a more accurate idea of God than my idea. (There are seven billion people on Earth; the odds of my idea being the most accurate are laughably small).
...does that answer your question?
Yes, it does, though those answers lead to further questions.
How can you gain information from a prediction you cannot test, until you die? Is there some way to test it? Or have you encountered personal evidence of an afterlife already?
Why does free will or an afterlife require a God?
It's hard to convey tone in text, but these are honest questions. If they make you uncomfortable, it's fine if you ignore them.
Regarding the sequences, you may find it easier to derive the same information from books popularizing a lot of the source material it is based on, if the sequences themselves turn you off.
