Luke 21:27

When conditions are at their worst, people living on the earth then will see the Son of Man coming in a cloud with power and great glory (Daniel 7:13; cf. Luke 9:36; 2 Peter 1:16-17). He will come to set up the messianic kingdom and to reign on the earth for 1,000 years (Daniel 7:14; Revelation 20:1-6). The cloud may be the Shekinah (cf. Acts 1:9-11).
