A book such as you hypothesize would be a great read. I’d love to hear/read the thoughts of others in this position.

On a non-mill point, though, there’s an interesting reflection on Peterson by iMonk. The guy (Peterson) is not your run-of-the-mill Evangelical (or one at all, as far as I can tell) but he’s got valuable things things to teach us.

Dunno?

a. Massive encouragement to evangelise, reform the church, transform the culture, in much the same way that Calvinism actually promotes evangelism (God has his elect/ the world will be saved, so get preaching etc.).

b. Patience in doing all the above (which means we can and infact must take our time off, observe the sabbath, be hapy to go long term on loads of things, read, study, leave things for the next generation, etc.).

That’s all.
Not to say Postmills always get this right, or that a/ premills can’t either. But, being consistent, postmillers should be like that.

I thought he was an interesting opposite to angsty, con-evo activism (‘if we don’t burn ourselves out for Jesus who will?’/ ‘no time to think about that, get those people into that lifeboat!’), but in the end felt that the two extremes probably need to be brought together in some sort of synthesis. [And I think postmillenialism could help to do this]
