6. What is the relationship between Matthew 24, Mark 13, and Luke 21; and what question should keenly interest us?

⁶ You will find their question and Jesus’ reply in Matthew chapter 24, Mark chapter 13, and Luke chapter 21.a

Did Jesus have in mind the tribulation that climaxed in 70 C.E., or was he speaking of the great tribulation that is still future in our modern times?​—Matthew 24:29; Mark 13:24.

It seemed also that the foretold celestial phenomena could be expected during the interval after the opening phase in 1914-18. (Matthew 24:29; Mark 13:24, 25; Luke 21:25)

Additionally, almost two thousand years ago, there was included in the Bible an accurate description of world conditions in this 20th century. (Matthew, chapters 24, 25; Mark, chapter 13; Luke, chapter 21; 2 Timothy 3:1-5; 2 Peter 3:3, 4; Revelation 6:1-8)

But what I say to you I say to all, Keep on the watch.”​—Mark 13:23-37.

18. How may we expect the “anguish of nations” to culminate? (Isa. 45:18)

¹⁸ After warning of “false Christs and false prophets,” many of whom have appeared in these final days, Jesus refers to fearsome sights in the heavens and to the “great power and glory” of his coming as the “Son of man,” when he executes judgment and gathers his own for salvation. (Matt. 24:24; Mark 13:26)

Heaven and earth will pass away, but my words will not pass away.” (Mark 13:21-27, 30, 31)
