a time of suffering that tests one's endurance, patience, and faith
corrective punishment to guide humanity. The Law of Karma works both individually and collectively. This can be realized by observing individual lives and also history. In fact, history is an especially good lesson to observe and learn from. If the human learns these lessons, he can create a proper environment to live in. Otherwise the suffering will continue to be on earth.
A period of time lasting 7 years, the first 3 1/2 years will be relatively peaceful as the antichrist rises to power. The second 3 1/2 years will bring the greatest suffering in human history as the wrath of God and the Antichrist is poured out on earth. (Dan 9:27) , (Mat 24:21)
