Thanks for your patience... like most, if I had complete control over scheduling demands, I would have retired, long ago to Tuscany...
You state, Waldo, that God would know your level of skepticism and provide adequate proof of Himself equal to the level of disbelief (unbelief?). I think that you may be speaking of "proof" when, in fact you are asking for "certainty". How is it,that a seemingly rational, thinking being, such as yourself (yes, I'm happy to grant that premise) can inquire of evidence available to all and yet, come to an entirely different conclusion as to it's "provision of certaintiy" than another, rational, thinking being (I present myself as such)?
Are there not an immense number of things in life that provide "proof" of their existence, yet one comes away as "uncertain"? Evolution, is one example, and among that elite, small handful of theoretical scientists that understand and argue the merits of the Grand Unification Theory, it's apparent that none are certain of their "proofs".
Sincerely, this is not an attempt to segue into another subject to avoid a direct answer to your important (and, I think possibly, a heartfelt) question. There's a number of arguments one can present, but this one is the most cogent to me...
"Yet even if God provided proof that was satisfactory to everyone, faith and trust would still be required to follow God. The atheist's question would merely change from "Why doesn't God prove his existence?" to "Why doesn't God explain why he did this and not that?" Atheists themselves would become theists, but not all of them would become Christians: one can believe God exists without believing he's worthy of worship, or that Christ's death atoned for our sins.
