There's a couple of hundred prophesies about Jesus, some obvious, some you'd never realise without it being pointed out.
If they were truly prophecies about Jesus, passed down from God, you would think it would be a matter of sufficient importance that he would ensure the prophecies were unambiguous and clear. In fact, being from God, you would expect them to stand out as a slamdunk of miraculous and inexplicable prescience.
Instead you have something that looks exactly like the handwaving after-the-fact postdiction of the likes of astrology and the quatrains of Nostradamus.
Why couldn't God do better than those deluded fallible humans? Because the bible was written by deluded fallible humans, and the God described in it is their invention. It's just so clear and obvious to someone without a pre-determined conclusion. Don't wheel in a load of special pleading and rationalisation. Don't load yourself up with all this cognitive dissonance.
We wouldn't have those expectations (omnipotent, omnisicient, loving) without the Bible telling us that's what God it like.
That's putting the cart before the horse. The only source material you have to base any of your expectations on is the Bible. If you're going to be reasonable and rational, you have to be able to trust what the Bible says. If the bible is demonstrably unreliable you just can't do that.
It goes double if the bible purports to be an expression of omniscience and infallible integrity. Any demonstrated shakiness or holes in the story immediately puts the lie to the entire premise. Given it's claims, the bible needs to be an awe-inspiring paragon of resplendent perfection. But it's not be any stretch. It's a mostly tedious and sketchy hodge podge of confusing inconsistent mythology, patched together over hundreds of years in several acts of historical revisionism aimed at wedding different religions together to maintain social stability.
God doesn't conform to our expectations or predetermined conclusions.
That shouldn't be used as a critical thinking ejector seat. Once you do that you're lost forever in the story, because then absolutely no amount of logical inconsistency, hypocrisy and self-contradiction can slap you in the face hard enough to wake you up to the fact that all of it is quite obviously the ad-hoc conglomeration of the imagination of several disparate groups of humans.
Say that I wrote a book about how I was the creator of the universe and I rebuffed any questioning of the veracity of claims by saying that it all makes sense, it's just that whenever it seems like doesn't, it means people aren't capable of understanding it, but that you should just trust me anyway. Given that situation, if you applied the level of rigour to which you hold the bible, you would be just a justified in believing my half-assed story as you would the bible.
