I agree that the question IS about God’s Nature.
however, let’s look a little closer at your supposition - That the Tribulation is the wrath of God.
It will be given to the “king” to do what he pleases - (this “king” of the earth at the time is the AntiChrist). This is the first half of the tribulation. This is NOT the wrath of God, it’s the AntiChrist’s wrath.
Now, IF the antichrist is decimating folks, who do you think he’s decimating? A house divided does not stand.
The whole idea that believers will not be harmed in any way is a pipe dream. Tell that to the 1st century Christians, and Christians being persecuted all over the world today.
The Church has always been a target for man/satan’s “wrath”.
If anything, the Church grows under such persecutions.
“THE” wrath (THE tribulation)is God’s. As bad as things have been and will be, we will not suffer the Father’s wrath.
HERETIC!
Simple definition of Dispensationalism: American Christians will be saved from trials because God knows they’re not ready to suffer or die like the true church always has.
