"Your materialistic world view cannot account for the metaphysical nature of reality."
Sure it can, and it does.
"Objective and universal standards of reason simply cannot exist in your purely material world, but you act as if they do."
Horse manure. More mystical nonsense. Objective standards and the supernatural are incompatible.
You presuppose the supernatural in your reply; otherwise, your protestations and mine are just the result of empty sensations created by the chemical reactions of brains. This would mean that you do not believe atheism because it is true, but rather because of chance concatenations of atoms. So your atheism ends up destroying rationality andobjective standards. If there is no God, then ALL abstractions are chemical epiphenomena, no different from horse manure, which means that you have no reason for assigning truth and falsity to those irrational physical forces and chemical reactions. It's the same as assigning truth or falsity to horse manure.
Of course you assume objective truth but your world view provides no foundation for it. You assume them because you are God's creature and live in His universe and you can't help it. Your knowledge of God is evident in your unacknowledged presuppositions, although not in your affirmations. You argue against God but you have to take him for granted to do so.
Cordially,
