The time period is irrelevant. God calls us to live the same in each time period, in season and out. (e.g. preaching the gospel when it is favorable and when it is not).
Hey, constantine turned the whole roman world Christian. Unless you’re Roman Catholic I don’t think you’d agree that was necessarily a good thing.
Regardless of what time period I would CHOOSE to live in, we are not called to transform culture but to preach the word in season and out. So apparently there will be no lasting ‘peace.’ since the Bible expects us to find that “evil men and impostors will proceed from bad to worse, deceiving and being deceived.” 2 Tim 3:13
And there is coming a great tribulation (unless you’re a full preterist, in which case you still aren’t promised the transformation of culture before the return of Christ).
To suggest otherwise is to go against Scripture. Period. We may win small battles here and there, but the primary battle is not social justice, the primary battle is for the truth of the gospel to go out and transform HEARTS... the ones God is calling to himself.
Re-phrased version of the question: Did you not answer the time and place question because it would force you to conclude that societies subject to Christ’s word are more prosperous, more peaceful, more loving than those who have not heard His word?
