Well, if I should have put "good life" in quotes before, then so be it. The underlying point that has been repeated many times is that our side holds that living a "good life" is not a cause of salvation. Perseverance is incident to salvation via the work of God's power within us.
If you equate "good life" with Godly life and suppose that a truly lost person can lead a truly Godly life, thus winning salvation, then perhaps we are farther apart than I had thought. :)
Again, I do sympathize with the fact that it may sound harsh to us humans that the non-elect can live any kind of life, or do anything they want to merit God's grace, and still be passed over. My answer is that the proper redressee on this point is not me, the messenger, but rather Management. We just work here, on this earth thingy. God's complete and perfect sovereignty remains intact, whether it sounds fair to us or not.
Again again, from our perspective, the whole world is a field of the elect.
