Introduction
The Mid-Tribulation Rapture theory (Mid-Trib) proposes that believers will be raptured at the midpoint of the Tribulation. This is to occur after the Antichrist is revealed but before God's full wrath. Believers will experience the first half of the Tribulation under the Antichrist but will be taken to heaven before the severe judgment of the second half (the Great Tribulation).
Proponents for Mid-Trib often cite Daniel 7:25, which speaks of the saints being given over to the Antichrist for a time, times, and half a time (three and a half years, the first half of the Tribulation), and Revelation 11:15, which describes the seventh trumpet, marking the shift from the Antichrist's wrath to God's. They also notes that the trumpet of 1 Corinthians 15:52 is the same trumpet mentioned in Revelation 11:15. The trumpet of Revelation 11 is the final in a series of trumpets; therefore, it makes sense that it would be “the last trumpet” of 1 Corinthians 15.
What is and What is Not the Wrath of God
Adherents to the "Mid-Trib" Rapture theory differentiate what torment comes from the world’s political structure (mainly from the Antichrist), from Satan, and the wrath from God. But they often fail to understand that God’s judgments can come from both Him directly (for example see Genesis 19:23-29) or indirectly (through a person, enemy, or other nation, for example see Isaiah 9:8-10:4). Regardless of how God brings judgment or wrath, the source is always God. Even though much of the wrath of God, as recorded in Revelation, will be sent indirectly through the “Antichrist,” it remains God’s judgment. The wrath that will be experienced in the seven-year period of the tribulation will come from God. Every one of the judgments including the “seal judgments” originate and are set into motion by God (see Revelation 6:16-17).
Regarding the Trumpet Blasts
The trumpet mentioned in 1 Thessalonians 4:16, is referred to as “the trumpet call of God,” which signifies the rapture and serves as a call of grace to all living believers. In contrast, the trumpet described in Revelation 11 signals impending judgment and represents a pronouncement of doom upon the wicked. Additionally, it is important to note that the seventh trumpet in Revelation is not the "last" trumpet in a chronological sense; Matthew 24:31 mentions a subsequent trumpet that will sound at the inception of Christ’s kingdom.
Shielded from Wrath
The Bible teaches that judgments from God typically have two elements, punishment and final consequences. Prior to final judgment God will punish all living unbelievers as identified in the tribulation period. Believers will be spared from the wrath as promised:
“Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God.” (Romans 5:9, ESV)
“There is therefore now no condemnation for those who are in Christ Jesus.” (Romans 8:1, ESV)
“and to wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come.” (1 Thessalonians 1:10, ESV)
“For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ, who died for us so that whether we are awake or asleep we might live with him.” (1 Thessalonians 5:9-10, ESV)
We see that the wrath of God is reserved for unbelievers.
“The one who believes in the Son has eternal life. The one who rejects the Son will not see life, but God’s wrath remains on him.” (John 3:36, NET)
“For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth.” (Romans 1:18, ESV)
“Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.” (Ephesians 5:6, ESV)
Regarding Revelation 13:7, some manuscripts omit the sentence about the saints and the conquering of them. But even it was true by the time the events of Revelation 13:1-10 occurred there would still be those that accepted Jesus after the rapture and those saints would face the wrath.
Conclusion
In Revelation chapter six Jesus begins to punish unbelievers (remember that if someone is not for Jesus is against Him, see Matthew 12:30; Mark 9:40; Luke 11:23). Believers will not experience any wrath from God as He has forgiven them and covered them in His own blood.
