Jesus speaks of not knowing how to interpret the SIGNS of the times, to the people who don't recognize His deity.
9-11 & the fall of Iraq (the location of ancient Babylon) are God's emergency "signs" & warnings of "the day of the LORD" when those on Earth who are not sealed by God will have a taste of Hell during the Great Tribulation for about seven years, as you can see here & toward the bottom of this page. "Shall evil befall a city & the LORD hath not done it?" (Amos 3:6):
14 The great day of the LORD [a phrase often used in the Bible to describe the time of Jesus' Second Coming and Jesus' reign] is near...15 That day is a day of wrath, a day of trouble and distress...
1:16 A day of the trumpet and alarm against the fenced cities, and against the
high towers. 17 And I will bring distress upon men, that they shall walk like blind men, because they have sinned against the LORD: and their blood shall be poured out as dust, and their flesh as the dung. (Zephaniah 1:14-17)
TO SEE HOW 9/11 IS PREDICTED BY GENESIS 11:1-9, REVELATION CH. 9-11 & CH. 17-18; AMOS 9:11, HEBREWS 9:11, JOHN 9:11, & REVELATION 9:11; ISAIAH 30:25; DANIEL 8; AND MORE, WHICH IS A "SIGN" THAT "THE GREAT DAY OF THE LORD...AGAINST THE HIGH TOWERS" (ZEPHANIAH 1:16) IS VERY NEAR, SEE:
