Revelation is kind of tough, don't you think? Are you saying you do understand all of Revelation?
I do think a lot of people though have missed the part about "at hand" and "shortly come to pass". I had missed it myself up until not too long ago but coming to pay more attention to those phrases did change my understanding of Revelation, as well as other passages outside of Revelation.
"let me know if you want more."
Sure, why not? Give me your take on Revelation and what you think "at hand" etc. means and whatever else. I'll read what you have to say. May not respond but I don't mind hearing your take on it.
