I have no issue with prophetic speculation that's educated and based on the scriptures, and that's what's happening in this video. I don't think he's got enough evidence to convince on the date he puts forward, but there's no harm in thinking and examining. The reason the Lord gave signs is so that His people would see and recognize those signs at the appropriate time. He does make one important point that is absolutely true. That is the Antichrist will appear before Messiah Jesus returns. This is clearly written (Matt. 24:15-31, 1 Thes. 2:1-4) and perhaps one of the most important things believers should be prepared to encounter.
