He is already here.
Technology lets us become aware of happenings same generation. Uhm… sometimes right away, but Truth is not recognized until we have enough context!!
Historically it was a long time before the signs were recognized. We don't have to wait so long, but if you are not already a watcher… be advised, don't be so literal in language translations. Feel the spirit. It is very real.
Hint… do not expect Him to be obvious. Believers have no need to know. Non-believers don't believe it anyway, so don't care. But when those possessed with the evil… see it, they demonstrate intense hate when they see the Light that you may not be seeing. Never in my many, looong years have I seen so much intense hate.
