Even though the last part of this video has been inadvertently cut off, Paul White gives an excellent explanation of these passages.
From Matthew 24: 27-30 we read:
Mat 24:27 For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be.
Mat 24:28 For wherever the carcass is, there the eagles will be gathered together.
Mat 24:29 “Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken.
Mat 24:30 Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.
