Not enough evidence?
When asked what he would say if upon death he found himself in the presence of God, Bertrand Russell famously replied that he would complain about the lack of evidence for His existence in this life. It is a common enough skeptical objection: if God really wanted people to come to a saving relationship with Him, why didn't He supply more obvious evidence of His reality?
It sounds plausible at first, but there are quite a few situations in which people have all the evidence they need to make an important decision, yet fail to act upon it.
Take smoking for example. The medical evidence is unanimous that smoking is a horrible habit and that it destroys your health, and often leads to deathly cancer. And this evidence is everywhere, printed on every single carton of cigarettes sold at legal outlets. The would-be smoker and the one who already smokes are both inundated with this evidence wherever they go. There are, to be sure, advertisements which make smoking out to be a 'sexy', alluring habit, but it's hard to believe that anyone really thinks that the social advantages of smoking mitigate against the disastrous medical consequences.
So if bountiful, clear evidence was all people needed to make the right decision, no one would smoke, or at least smoke for very long. But of course millions of people continue to smoke, often for their whole lives, and continue to get sick and die from it. What good was all that evidence to them? It seems that people find ways to rationalize away even the strongest evidence for a course of action they are not willing to undertake. When people break the habit, it is usually not because they have suddenly come across all the medical research detailing how harmful smoking is, but because they reach a critical moment in which the truth they had been suppressing suddenly dawns on them. It is more about a transformation of the will than the intellectual accumulation of evidence.
I am still sympathetic to those whose intellect gets in the way of embracing Christianity. I experience the anguish of the 'not enough evidence' protest often enough myself. Am I really supposed to radically commit myself to a worldview that promises discomfort and conflict in this life, when I am not 100% sure that it is true? But then I get to thinking, what if I and everyone else are more like smokers than we care to admit? What if for some reason we just don't want Christianity to be true, so that we would rationalize away even the strongest, clearest evidence for God's existence?
I don't know that the above considerations actually strengthen the evidential case for Christian theism, but at the very least they should give pause to those who press the 'not enough evidence' objection too far.
