If someone asks a general question, viz., "Is there evidence for Christianity?" my reply would be that it depends on the specifics. For example, is there evidence that the disciples lived, the answer is, yes. Is there evidence that a historical Jesus lived, the answer is also yes. There are various kinds of evidence in the Bible that support its historicity. However, many people who ask this question want to know if there is enough evidence to warrant belief in Christianity as a religion. For example, is there evidence that the God of the Bible exists; or is there evidence for the resurrection; or is there evidence that Jesus actually performed miracles, etc.
Before going on let's examine briefly some views on faith. Some Christians believe that one's faith should be backed up with good reasons or good evidence. These Christians give logical arguments for the existence of God, and for the physical resurrection of Christ. Dr. William Lane Craig is a Christian who happens to also be a (analytic) philosopher and a Christian apologist. Dr. Craig is an example of someone who gives arguments defending the Christian faith. Thus, people like Dr. Craig believe that one's faith is supported by good reasons.
There are also those within Christianity who believe that faith in itself is enough, i.e., one doesn't need good reasons or good evidence to support their faith. Many Christians believe that this kind of faith is what's central to their belief. Therefore, it's not a matter of having good arguments to support one's belief, it's a matter of exercising one's faith, or trusting in God or Christ. When exercising just faith in Christ one's mind is illumined to the truth by the Holy Spirit.
I will start with this post first as a kind of introduction to what follows.
We have been programmed how to think by social pressures and influences. Our psychological mechanisms prevent us from forming "unpopular" thoughts almost immediately, because it can be dangerous to our well-being.
Is it logical to believe that a finite creature can measure, and perceive something that is infinite? It shouldn't be, but our ego tells us it is possible, and ignores the fact that Something like an Omnipotent, Omnipresent and Omniscient God of gods would fail to be
unperceivable in some ways even to the gods! Indeed, in the Apocrypha, the archons, principalities, angels and powers also call the Lord of Spirits (God of gods) the "[Great] Invisible Spirit."
Yet, we use metrics to determine the immeasurable - because we are deceiving ourselves, and see no issue with it.
Now, I am not saying that we should operate with no evidence at all; God didn't make us to be
blindly faithful. He gave us reasoning minds and intellect to
come to a conclusion based on our experiences. The bible is full of charges to us by God to use our "head," and really
think about what we are doing. We don't appreciate it, nor do we see it as profitable.
For example, God told the Israelites that they would have HIM as their God - they wanted to be like the world, and have an
imperfect, man king as their representative. (How did that work out?) Still, God indulged our sophomoric cries to Him so that we would
learn from those mistakes.
There is plenty of evidence to make an informed and astute decision about this world, the world beyond this world, and the compositions thereof - including The Creator. However, we are in enmity between what is right, and what is acceptable. Spirituality is an upward battle for
carnal entities; which is why our success in overseeing headships of
religion are abysmal at best.
So, it all comes down to blinding ourselves. We know in our
second brain (heart) what is right and wrong; we erroneously use our primary brain to rationalize everything according to our paradigms and circumstances. I was never forced to learn about God. I wasn't exposed to any one religion; in fact, I have been exposed to many religions. I didn't entertain, and then accept "Christianity" until
after I finished University - a stark contrast to the cliche that religious folks are unintelligent, sheltered and unworldly in thought. He actually gave me "proof," which I consider with hindsight a bitter-sweet thing: I have
luxury of denying Him, His existence and the existence of the entire creation (including things considered ridiculous and fantastical.) But, I had to make a mental submission, and decision to realize that my alleged "intelligent" brain absolutely has no idea of the wonders and elements that make up existence. (This is another cliche usually associated with mystics and gnostics: to abandon everything you know in order to
know.)
It depends on you. God - the real God of gods - won't force you to believe in Him. He, and the entities that worship Him are gentlepersons. That is why
demons/gods invade, while one has to
make a conscious choice to let God and His Choir in their life.
