In the sixth seal judgment of Tribulation, the sun goes dark and the moon turns to blood. Are these the same signs Joel is writing about in Joel 2?
Joel's prophecy in chapter 2 describes events during Tribulation, and some sound very similar to those described in the sixth seal judgment of Tribulation, but these are actually different judgments. In Revelation 6 we read:
These events take place in the first half of the Tribulation. Joel describes similar events:
The book of Joel describes events during Tribulation, and like in Revelation, Joel describes moments of God's wrath when the sun is darkened and other signs appear in the sky. Nevertheless, these signs are not the same as those described in Revelation 6 because the context of the two passages does not match.
In Revelation 6, the events of the seal judgments occur at the very beginning of the seven-year Tribulation, while the events described in Joel are associated with the very end of Tribulation. In Joel 2:32 we read that the signs in the sky will immediately precede the rescue of Israel, but the rescue of Israel occurs at the very end of the Tribulation, according to Zechariah 12-14. Therefore, the signs in the sky in Revelation 6 are different than the ones that are described in Joel 2.
In fact, these types of signs do appear numerous times during Tribulation. Across the Old Testament prophets and in the book of Revelation, we can find at least four separate occasions when blackouts or other signs in the sky occur during Tribulation. The book of Joel describes two such occasions, one in chapter 2 and another in chapter 3.
Therefore, the blackout described in Joel 2 is the blackout associated with the fifth bowl judgment near the end of Tribulation. Soon thereafter, the nation of Israel will be saved as described in Zechariah 12. The blackout of the sixth seal judgment is an earlier moment in Tribulation.
