When were all who beliv HIm takrn up to be with Him?
It happened in 70 A.D. just like Jesus said it would. Let me give you 12 comparisons between Matt 24 and 1 Thessalonians 4:13-5:8 that I think will show that Paul is talking about the same event Jesus was in the Olivet Discourse.
Mt. 24 = 1 Thess. 4: 13-18 & 5: 1-8
1. Christ Returns from Heaven Matt 24:30 = 1 Thess 4:16
2. With Voice of an Arch Angel Matt 24:31 = 1 Thess 4:16
3. With the Trumpet of God Matt 24:31 = 1 Thess 4:16
4. Caught/Gathered Together with/to Christ Matt 24:31 = 1 Thess 4:17
5. “Meet” the Lord in the Clouds Matt 24:30 & 25:6 = 1 Thess 4:17
6. Exact Time Unknown Matt 24:36 = 1 Thess 5:1-2
7. Christ Comes as a Thief Matt 24:43 = 1 Thess 5:2
8. Unbelievers Caught Off Guard Matt 24:37-39 = 1 Thess 5:3
9. Time of Birth Pangs Matt 24:8 = 1 Thess 5:3
10. Believers Not Deceived Matt 24:43 = 1 Thess 5:4-5
11. Believers to Be Watchful Matt 24:42 = 1 Thess 5:6
12. Exhorted to Sobriety Matt 24:49 = 1 Thess 5:7
12. Son/Sunlight Shining From E. to W. / Sons of the Day Matt 24:27, 36, & 38 = 1 Thess 5:4-8
Remember Jesus said this would happen to His generation in the Olivet Discourse. (Matt 24:34)
