Charles Spurgeon Commentary Matthew 24:29-30

"But immediately after the tribulation of those days the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: and then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming on the clouds of heaven with power and great glory." — Matthew 24:29-30 (ASV)

Our Lord appears to have purposely mingled the prophecies concerning the destruction of Jerusalem and His own second coming, so that there should be nothing in His words to satisfy idle curiosity, but everything to keep His disciples always on the watch for His appearing.

These verses must apply to the coming of the King at the last great day. There may have been a partial fulfilment of them in the tribulation that came upon His guilty capital, and the language of the Savior might have been taken metaphorically to set forth the wonders in the heavens and the woes on the earth in connection with that awful judgment; but we must regard Christ’s words here as prophetic of the final manifestation of the Son of man coming in the clouds of heaven with power and great glory.

There will be no further need of the sun and the moon and the stars, when HE, who is brighter than the sun, shines forth in all the glory of His Father and of His holy angels.

Christ’s coming will be the source of untold joy to His friends, but it will bring unparalleled sorrow to His foes, then shall all the tribes of the earth mourn. When Jesus comes, He will find the nations still unsaved, and horror will be their eternal portion.
