You said: "And your questions about “who restrains sin,” “who judges Israel,” “who handles earthly duties,” and “what Jesus does for 1,000 years” only expose the problem: your system requires answers Scripture never gives, because Revelation 20 never describes mortals living, sinning, repopulating, or needing judges during the millennium — it describes the souls of martyrs reigning with Christ, Satan restrained, and then Satan released for a final deception before judgment."
Your system says to ignore scripture. While Revelation 20 doesn't describe what happens during the 1,000 years doesn't mean that the Old Testament and specifically, Isaiah, should be ignored and erased. Especially after Jesus specifically told His disciples that He must fulfill ALL THINGS THAT WERE WRITTEN in the Old Testament.
You said: "The release isn’t a mystery; Paul already explains it in 2 Thess 2: evil reaches its final, climactic outbreak before Christ destroys it. The restraint isn’t Jesus “waiting in heaven”; it’s the same restraint Paul describes in 2 Thess 2:6–7, the sovereign limitation of satanic deception during the gospel age."
So, in your view, evil reaches its peak before Christ returns to judge all of the people and destroy the earth. Yet the Bible tells us that there is a time of peace where people will know who Jesus is and they will go about life living in righteousness, but still sinning, dying, and repopulating. How do they get to that point before Jesus' Second Coming?
