Jesus listed these events as part of the sign: great wars, famine, pestilences, earthquakes, persecution of his followers, increasing lawlessness, and nations in anguish, not knowing the way out of their dilemma.—Matt. 24; Mark 13; Luke 21.
... So it is just as Jesus taught his followers—he is using his “faithful and discreet slave” organization to educate people in the truths of God’s Word. (Matt. 24:45-47)
