>Is there any real, persuasive evidence of the supernatural you guys could give me?
The existence of anything.
>Does prayer actually change anything, or have any effect at all for that matter?
If God inclines to hear the prayer, yes. Meaning if it is done by a saved person in the name of the Savior, Jesus Christ, the Son.
Proverbs 15:8
>The sacrifice of the wicked is an abomination to the LORD: but the prayer of the upright is his delight.
The upright here being Jesus Christ, our mediator to the Father. And I would also add here, more than anything else, let the will of God be done.
>Are there serious, irreconcilable contradictions in the Bible?
There are plenty of what may appear to be contradictions, unless and until you have the proper understanding of how both Biblical statements are true. I guarantee you if you find something like that, it has been asked and reflected on many times before. But often times these so-called contradicting statements actually help drastically to narrow down the truth as the only possible way to explain these statements in harmony with each other, which is sometimes what makes Bible study so interesting.
>If there are, is Christianity still viable as a belief system, could it still be reasonably defended?
The whole basis of Christianity is the truth of the fact that Jesus Christ is still alive right now. That he is currently ascended and will return. That God came in the flesh, died and resurrected, and that therefore, so will we too in like manner by the same operation, whosoever believes in truth this shall occur. Which is what the word of God has first been given to testify, and to teach and explain for us. And really, no matter what denomination, everything is predicated on that fact. This is what Paul explains in the chapter of 1 Corinthians 15 if you want to know where it's coming from.
