Week seventy is a scriptural reference to the last seven years of the Earth as we know it. Those seven years will be the time of the antichrist, the apocalypse, and great horror and death.
But they also bring in a new and better world where truth and righteousness prevail and man’s long-sought utopia and longevity of life will be found.
Thus, week seventy is both fully good and fully bad at the same time. Bad for all those who have taken advantage of the weak and poor; but good for all those who have longed for justice in a fallen and unjust world system.
