Moses did not understand the things we know today - FB conversation

I am enjoying one of the most amazing lightning storms as it passes right over my house. I'm getting just a glimpse of how Moses must have felt on Mt. Sinai!!! — feeling awesome.

A.M.: Yes but unlike Moses, you understand lightning. Though possibly a similar experience, your feelings of awe and amazement are probably not the feelings of absolute terror that Moses must have felt.

Me: Moses didn't understand lightning?

A.M.: Prior to the mid-1700s(AD), most of the world did not understand lightning. So i cant imagine that Moses of 1400BC understood any possible scientific explanation for lightning.

Me: You imputed "absolute terror" to Moses, which suggests that he was some sort of cave man. Moses was treated as the son of Pharaoh, and was probably one of the most educated men alive. Suggesting he was in ignorant terror is more than presumptuous.

A.M.: Still, educated or not, assuming that standing in the presence of God is in fact anything like a lightning storm, anyone would be terrified. I never implied ignorance was a word befitting the messenger of God.

Me: Not meaning to dispute with you, but your last comment does not bear any resemblance to your first.

A.M.: Brett, i apologize for the lengthy argument on your status. I'm sure your experience was awesome. I did not intend to offend anyone. You know your faith well enough to understand what the Scriptures say about Moses' experience. i was just pointing out a mild difference, which i'm sure you were already aware of.

B.H. No apologies necessary. I am actually kind of enjoying the discourse.

Me: The goalposts were moved, since we aren't talking about what Ashtyn originally posted. I would therefore call it a parallel conversation.
