I'm something of a mugwump on the Reformed-Arminian food fights, since I appreaciate some of the points of each side and have trouble with each side as well.
The one that troubles me on the Arminian side is the idea that someone could lose one's salvation, that it's an ongoing process rather than a one-time say-that-prayer-and-you're-in event.
For me, that gives me something of a death wish, wanting to die sooner rather than later in order to lock in my salvation. I recall having to leave a service four years ago after just getting let go from Sullivan U rather than have suicidal thoughts, that my less-than-fruitful life wasn't worth the risk of screwing up somehow and not making the works grade.
However, I think the works that Reformed folks are worried about are much more an outgrowth of a saving faith more than a requirement for it. There doesn't seem to be a grading curve for salvation, so some positive change and some positive effort to expand the Kingdom is more than enough. No change and no effort would indicate someone who hasn't really gotten the message in the first place.
That "working out your salvation with fear and trembling" shouldn't cause a death wish, for so many verses point to faith being the primary issue. John 3:16 didn't say that we have eternal life if we score a 70 or better for the course.
