Wesley's approach was different. He was just as confident as Camping that the Judgment would come, though he certainly agreed with Jesus (instead of Camping) that no one did or could know exactly when. But the news of this judgment for Wesley was really good news-- and not just for the "elect" by and by, but for everyone, here and now.
Perhaps one might say that Camping had or seemed to proclaim a "deadly hope," while Wesley had a "living hope," a hope for the restraint of societal evils generally, and a hope for the full salvation of all who would receive it by faith and continue to grow into a "spotless love, the full image of God renewed in the heart."
Contemporary Challenges to "The Judgment"
Except for scientism. Because here we have a serious problem. Until the advent of quantum physics, and to a large degree despite it since then, science operated by thinking in either/or ways. Either X is the case OR Y is the case. If X is the case, and Y is fundamentally different, then Y cannot be the case at the same time. This led to a serious war and often divorce between scientism (if not science) and religion beginning in the late 19th century and continuing to this day. The scientism that pervades Western thinking must admit that if the universe is infinite and non-ending, as far as science can tell, then there's no way Christ or any person or being could end and start it over again. Science (scientism!) is right, religion (Christianity) just plain wrong-- if not ridiculous or even dangerous (a la Hitchens and Dawkins).
I raise these challenges to our doctrinal standard (Wesley's sermon) not in any defensive way.
Nor do I raise them to reject our doctrinal standard. (I embrace it!).
I raise them for the real challenges they are, challenges that appear pervasively in our own thinking, even within my thinking about these things.
