I had one of those spiritual checks inside when reading your closing lines. Amos 5:18 is the scripture you are relaying, but when taken in context, it is clear to the reader that Amos, the prophet of the Lord, is talking to the mockers/scorners of his day. He was admonishing them for their remarks about the Day of the Lord, as they will not be finding it so agreeable once it arrives. He was not talking about believers and the growing excitement we feel as we watch the world events unfolding. After all, the Lord told us to watch. Do you think He wanted us to be unmoved by what we see? We are to be excited at His soon return for us, as well as moved with compassion for those who are so desperately not ready.
