I think He does both. I think He has provided both public proof in the form of public miracles which show His power and public prophecies which show His foreknowledge. As well as proving Himself on a personal level with individuals.
I do think God is provable. But just like there are some people who refuse to believe that man walked on the moon, you can't get everyone to spend the time to consider the evidence, or to believe the validity of the evidence.
Believing or not whether man walked on the moon doesn't really have any ramifications for how we live. Believing or not in God has major ramifications.
Unfortuately I think many people allow the ramifications to influence their objectivity in weighing the evidence. Hence, instead of truly considering the evidence, people choose what they want to believe first and then see the evidence through rose colored glasses.
To be sure, Atheists aren't the only ones who do that. Christians do too. And it accounts for many of the differing interpretations of scripture that are out there.
Perhaps you along with Phaedrus could be the first in history (that I’m aware of) to do so. I’m sure virtually everyone would consider that worthy of publication.
Yes, and also: You can lead a horse to water, but you can't make him drink.
