Do you have a Cliff-Notes version of your objections to Universalism?
So, you want a Cliff Notes version, huh? I don't have one. :) But I'll make the attempt.
The reason is simple: it's not a view about who is going and who is not ... it's about humanity as God made it versus humanity as we have come to know it. We have learned to place value on man because of man himself and this is why we always hit a brick wall when we attempt to figure out the WHO and WHY or WHO NOT and WHY NOT. But the value is only found in God Himself.
The problems I've encountered in sharing my thoughts about this come from the fact that it doesn't answer the basic issues that we demand to have answered. Why not? Because those issues are bogus. We're trying to figure out who among men will get redeemed, but the old had to be done away, NOT reworked. Our problem is attached to the fact that we try to reinterpret "new" to encompass our experience of the old. Is this making any sense at all ... or is it adding to the confusion? :)
