Reality Check: What Must Be the Case if Christianity is True?

I'm going to start a series of posts describing what must be the case if Christianity is true. When done I'll put them all together so Christians can see the formidable obstacles there are to their faith at a glance.

1) There must be a God who is a simple being yet made up of three inexplicable persons existing forever outside of time without a beginning, who therefore never learned anything new, never took a risk, never made a decision, never disagreed within the Godhead, and never had a prior moment to freely choose his own nature.
