A close examination of instances of the wrath of God during the tribulation (in the book of Revelation), reveals that, in every instance, God’s wrath is poured out, not on the true believers of Christ, but on the followers of the antichrist or beast.
So, yes, I agree with you, God’s wrath is not appointed to his own. If you want, I can produce plenty of evidence of the wrath of God taking place while God’s people are still around to witness it. The plagues of Egypt, for instance. Which, by the way, is the figure that is used in Revelation for Christians who will go through the endtime tribulation.
The plagues of Egypt? And how many thousands of years did the plagues of Egypt occur before Christ came on the scene?
There were no Christians around during the plagues of Egypt because there could be no Christians before Christ.
Therefore, Christians did not suffer through the plagues of Egypt and did not suffer that wrath of God.
