Suppose we consider the Bible to be just like any other text. Now, most texts don’t make claims about themselves, but the Bible does. The Bible claims to be a message from God to man, for the fulfillment of man’s calling and the satisfaction of God’s desire to be one with man. So it would make sense to evaluate this claim about itself that the Bible makes.
How do we evaluate the Bible’s claims? I don’t think we simply take the Church’s word for it. Well, we might look at history. Did Jesus really live? Was he crucified? Yes. This is one of the most widely attested facts of ancient history. The only reason it is at all controversial is because people pretend like the Bible is *one *book. Numerous books of the Bible independently confirm Jesus’s life and death. (As do other historical sources).
Of course, they also confirm his resurrection. This is an extraordinary claim, so we shouldn’t just immediately accept it. But history also tells us that, in the first generations of Christians, hundreds of them died for the faith. Would you die for something you knew was a lie? Are there other events in history where such a diverse group of people were martyred for something they knew was a cooked-up story?
This sort of evidence brings us a long ways to believing in the resurrection, I think, but maybe not quite there. Now we have to do some hypothetical thinking. Suppose there is a God, and suppose Jesus lived and was resurrected, and sent the Holy Spirit. If that were all true, and the Bible were all true – these are just "if"s, mind you – then God would provide the power of faith to everyone who asked, so that we could believe these things. Even the resurrection.
Now ask yourself: do I have that power of faith? Ask for that power of faith. Faith in Jesus, in his death and resurrection, which precedes faith in the gospels.
This is what I have done, and I have found in myself the power to believe the unbelievable, that Christ was raised from the dead. Blessed be God!
Notice that I never asked you to believe something without evidence, in this post. There is the evidence of history, and then there is the evidence of faith, which is manifested in the indwelling power of God. Hope this helps!
P.S. By the way, I tend to agree that claims to infallibility are incoherent. But that’s not really relevant to the evidence for Christianity.
