"Spiritually speaking, he can experience the color red even without having any of his five senses by praying to God. God can do anything."
Prove it!
Otherwise its dogma at best.
Here is another thought. You suggest that IF god wants to, "he" could, whith the snap of is finger (I assume you think god has fingers along with that flowing white beard of his), allow someone to experience colour who was blind. What would cause him, then, to allow blindness in the first place (seeing as he controls everything in your opinion)?
So is god exact or is he moody? Does he follow a strict and exact plan or does he mix it up? Does he say John you get to see and Beth...sorry Beth I choose you to be blind...just because? Heck I am god...I'll do what I want and if you don't like it tough.
