2 Thessalonians 2:1-12
English Standard Version
The Man of Lawlessness
2 Now concerning (A)the coming of our Lord Jesus Christ and our (B)being gathered together to him, we ask you, brothers,[a] 2 not to be quickly shaken in mind or (C)alarmed, either (D)by a spirit or a (E)spoken word, or (F)a letter seeming to be from us, to the effect that (G)the day of the Lord has come. 3 (H)Let no one deceive you in any way. For that day will not come, (I)unless the rebellion comes first, and (J)the man of lawlessness[b] is revealed, (K)the son of destruction,[c] 4 who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, (L)proclaiming himself to be God. 5 Do you not remember that when I was still with you I told you these things? 6 And you know what is restraining him now so that he may be revealed in his time. 7 For (M)the mystery of lawlessness (N)is already at work. Only he who now restrains it will do so until he is out of the way. 8 And then (O)the lawless one will be revealed, whom the Lord Jesus (P)will kill with (Q)the breath of his mouth and bring to nothing by (R)the appearance of his coming. 9 The coming of the lawless one is by the activity of Satan (S)with all power and false signs and wonders, 10 and with all wicked deception for (T)those who are perishing, because they refused to love the truth and so be saved. 11 Therefore (U)God sends them a strong delusion, so that they may believe (V)what is false, 12 in order that all may be condemned (W)who did not believe the truth but (X)had pleasure in unrighteousness.

Daniel 12:9-10
New King James Version
9 And he said, “Go your way, Daniel, for the words are closed up and sealed till the time of the end. 10 (A)Many shall be purified, made white, and refined, (B)but the wicked shall do wickedly; and none of the wicked shall understand, but (C)the wise shall understand.

So a plain reading of this verse suggests an early to mid 7 years reign of the AC beast group before the rapture. Perhaps when the 2 witnesses get killed and then are raised up...everybody else Christian, (dead in Christ first then the rest) goes up.
