When do the cosmic signs in Matthew 24:29 occur?

The cosmic signs of Matthew 24:29 occur immediately after the tribulation of those days. They follow the final seven years of prophecy and the horrors of tribulation, when the sun is darkened, the moon gives no light, the stars fall, and the powers of heaven are shaken.

Les explains that Matthew 24 is tribulation, covering the final seven years of prophecy. Jesus uses the lightning analogy: lightning in the east means the storm has passed, so when the horrors of tribulation are past, the cosmic signs come. Verse 29 says, “immediately after the tribulation of those days,” the sun is darkened, the moon does not give her light, the stars fall, and the powers of the heavens are shaken. Les notes these are part of Old Testament prophecies and that such outer-space phenomena indicate the end is near; even Old Jupiter was a little preview, and seeing more of these phenomena assures us time is short.

Matthew 24:29

Immediately after the tribulation of those days shall the sun 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:

Are the sun, moon, and star signs in Matthew 24:29 Old Testament prophecies?

Yes, those celestial signs—the darkened sun, moon without light, falling stars, and shaken powers—are part and parcel of Old Testament prophecies. They occur immediately after the tribulation of those days within the final seven years of prophecy. Scripture presents them as events indicating the end is near, and they are not isolated but integral to the prophetic timeline.
