All this is fine teaching but while the antichrist will likely use one of these systems, these are NOT, at this point, the "mark of the beast." It's about taking HIS mark, a mark of allegiance. That cannot happen if he is not publicly on the scene. Hand scanning veins, that's nothing. Where is his mark in that? If he uses this current technology, his mark will have to be encoded into it, because you can't buy or sell (again) without HIS mark.
Keep on preaching it, Pastor Crone! I appreciate your work and your videos!
