Matthew 24:7-8, 14

For nation will rise against nation, and kingdom against kingdom, and there will be famines and earthquakes in various places. But all these things are merely the beginning of birth pangs [of the intolerable anguish and the time of unprecedented trouble].

This good news of the kingdom [the gospel] will be preached throughout the whole world as a testimony to all the nations, and then the end [of the age] will come.
