Millennial Kingdom led by Jesus begins within twenty years?

If I could convince people that the Millennial Kingdom led by Jesus begins on earth within twenty years, would they change anything in their life? Keep in mind, that the great trial for everyone living on earth even begins some seven years sooner. First, God will send His two witnesses to first tell the world the truth but the world will hate them and wish to kill them but any harm directed toward them will fall on their own head.

These two prophets of God will have the power to smite the nations as often as they wish (Rev 11:6). That being true, the reality than is that those not in Christ will experience the start of this great trial on earth within the next 10 to 15 years.
