If a blind man or woman from birth, nevertheless comes to strong faith in Christ(Fanny Crosby the famed hymn writer is one), what “imagery” can such an one “relate” to?
When Christ healed one blind man, he did so in two stages...he first asked the man what he saw and the man replied...”I see men as trees walking” Christ touched the man again and he then saw normally. The man in question had never seen anything, so Christ had to impart wisdom so that that the man could relate to the world as a sighted man would see it apart from the touch and smell and hearing sensory derived mental symbolism he had developed to adapt to a world he could never see before.
That’s why optical imagery isn’t as important in the spiritual state of things...and why God laid down precepts against graven images...sometimes what you see can get in the way of true spiritual sight!
And I have seen people go up and touch the crucifix to venerate the image of Christ.
