Matt. 24:29 and Mark 13:24-25 say that the signs of the sun, moon and stars occur after the tribulation. But Joel 2:31 says the signs in the sun, moon, and stars happen before the Day of the Lord. My question is do the signs in sun, moon, and stars occur after the tribulation and before the start of the 1000 year reign of Christ as Matt. 24 says, or before the Day of the Lord as Joel 2 says?
The passage from Joel 2:31 refers to Rev. 6:12-14. This is the 6th Seal judgment which takes place before the Great Tribulation begins. Then there are the signs you mentioned that occur in conjunction with its end. The Sun and Moon also give signs through out the last seven years, such as in Rev. 8:12 and Rev. 16:8. So it’s not one or the other but both.
