Those men you heed simply came up with that "Pre-Wrath" label, especially since they falsely teach it means being raptured PRIOR to the "great tribulation". Here is where Jesus taught the "great tribulation" would start...
Matt 24:15-21
15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand
16 Then let them which be in Judaea flee into the mountains:
17 Let him which is on the housetop not come down to take any thing out of his house:
18 Neither let him which is in the field return back to take his clothes.
19 And woe unto them that are with child, and to them that give suck in those days!
20 But pray ye that your flight be not in the winter, neither on the sabbath day:
21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
KJV
Even per Daniel 7:21 about the coming false one being given to make war with the saints, that is what that beast of Revelation 13:4-8 also is to do, and will have power for 42 months, the same time the Gentiles of Revelation 11:1-2 are given to tread the holy city (Jerusalem), which is the same timing of 1260 days God's two witnesses are given to prophesy against the beast in Jerusalem. That... is the latter half of Daniel's symbolic "one week" of Daniel 9:27, which is equal to 1260 days, or a time, times, and half a time. That is the time of "great tribulation" Lord Jesus forewarned about in His Olivet discourse above. It's start He marked by that coming false Christ placing that "abomination of desolation" in a new temple in Jerusalem. That is the MID-TRIB timing, or what those men you follow call the "Pre-Wrath" timing, and is NOT when Jesus comes to rapture His Church.
Those men are lying to you.
