I'm not hiding behind anything, friend. I believe in order to understand. Belief is always the ultimate starting point of knowledge--"I believe in order to understand," as St. Anselm famously put it.
A thing can be clear in and of itself (perspecuity) even though a given subject is unable clearly to see it (perspicacity). So how do the scales come off?
Yes, the subjective difference is faith. Faith comes by hearing and hearing by the word of God, which is precisely why I am sharing it--in hopes that others will believe as well.
"All the riches of wisdom and knowledge are in Christ."
