At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man coming on the clouds of heaven with power and great glory.
The sign of the Son of Man will appear, the earth will mourn, and he will come on the clouds with power and great glory.
The verse presents the visible arrival of the Son of Man.
26So if they tell you, ‘There He is, in the wilderness,’ do not go out, or, ‘Here He is, in the inner rooms,’ do not believe it. 27For just as the lightning comes from the east and flashes as far as the west, so will be the coming of the Son of Man. 28Wherever there is a carcass, there the vultures will gather. 29Immediately after the tribulation of those days: 30At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man coming on the clouds of heaven with power and great glory. 31And He will send out His angels with a loud trumpet call, and they will gather His elect from the four winds, from one end of the heavens to the other.
