The 7th trumpet happens mid trib. Right after the abomination of desolation. Just prior to the vials of wrath being pored out. So many have confused the tribulation of saints or persecution of the church with Gods wrath being poured out. They are two separate things. The antichrist will make war on the church but gods wrath is pored out after he gathers the saints. I have studied this subject more than anything else in my entire 40 years on this earth. C.I. Scofeild and John Darby were heretics.
