I agree with the effects of Satan on our lives. Is Satan real? Yes. Does he "come as an angel of light to fool even the very elect if that were possible"? Yes. (And this is where I must add that translating the Bible words - both Hebrew and Greek - is not an exact science. S, https://eitan.bar/articles/hebrew-word-study-serpent-nahash/) Anyways, in the context of the entire Bible, I lean towards the description of Lucifer as originally a beautiful angel, fallen, cast out, jealous of the Creation, transforming himself into an angel of light , "nahash" - the shining one. We are so distracted by shiny objects, - even as babies. As we grow that syndrome seems to remain constant, even though the shiny objects change.
