1)Is it fair to say that amillenialism says God will continue to save people and shed common grace around them right in the midst of the evil decaying world system but that the proportion of those saved will probably not increase (in relation to "the world")?I think the folks who talk about "optimistic" and "pessimistic" are referring to what life in this world is like, so if some of us don't think the present millennium means raging political success, we're pessimists. I rather resent that - it really doesn't seem as if Scripture is encouraging us to have such an approach to the success of the Gospel, as if its all about our political success now. (BTW, the pentecostals got into "dominion theology" a variety of postmill while I wasn't lpaying attention; I thought they were all solidly Dispensational.) The Scripture says in this world we will have tribulation - which can mean political persecution as well as other things. Yet even in those circumstances the Gospel continues to spread. Of course, amills beileve that eventually things will get worse, and no one wants to hear that. But I don't feel it's too optimistic to say it never gets better than this, I'm looking forward, optimistically, to the new heaven and new earth, where righteousness dwells. That doesn't excuse inaction in sharing the Gospel and helping our neighbors and trying to restrain depravity as God allows us.
2)Would amillenialsim tend to say that things will get better and better in the church?
3)Would an "optimistic" amillenialist see the proportion increasing over time?
4) Any idea if the classic view tended either way ("optimistic"/"pessimistic") or is this a recent, unhelpful distinction?
Right on!
If we asked all those who believe in a millennium but did not believe in the successful advance of the gospel fully according to God's plan to leave the room, then we'ed still have all of us in attendance; none of us would leave. As a so-called pessimistic amillennialist I am fully persuaded, convinced, that the gospel will advance just as God has planned it, and that sin can not stand in its way.
This is not about who is more optimistic about the advance of the gospel; it's only about how that will happen. There's nothing inherently less optimistic in amillennialism than in postmillennialism; and permillennialism deserves the same respect in that department.
All right! A JohnV post!
I get tired of Postmills bringing out the whole 'optimistist' vs. 'pessimist' false dichotomy. It appears to be a similar tactic as the Dispensational saying, "If you believe like I do you won't have to suffer through the Great Tribulation!"
Is the account of Gideon only needing 300 men to defeat the Midianites who 'lay along in the valley like grasshoppers for multitude' pessimistic?
If the Lord chooses to pare down His army to but a few in order to win the ultimate battle, it is not pessimistic. It is glorious. If it brings God greater glory then it is in fact, 'optimistic'!

(That is as close to a 'tongue in cheek' emoticon that I can find)
