I wouldn't say all those who believe in eternal security do nothing; but they automatically assume anyone who doesn't buy into eternal security is working for salvation. If they do works it's okay, but if anyone else does good works it's not okay. It's a nice manipulation tactic.
It's kinda frustrating, but we as lowly pew-warmers can make a difference if we're willing to go outside the 2,000-year-old failed church system. We can also use the buildings, equipment, and expensive programs already in place. We just have to find a way to get past the heirarchy at the top.
It shouldn't be too hard to do, since most are either asleep at the wheel or busy writing books.
