LOL, your Grace is better than their Grace? But of course - that's why you're going to heaven, and they're going to hell. Right?
It's okay though, because they think the same of you.
Personally, I'm going to follow the global warming climate change entrepreneurial model, and start a Grace Credit Bank. That way if I invest in both Catholic and Protestant Grace Credits, I've got them both covered. Even better, I can sell my excess Grace Credits on the open market, and then reinvest the profits into my own Grace accounts.
Because really, at the end of the day, the bottom line take home is that God is an accountant, and when you die it's like an audit, and He sits down with a Bible concordance and finds line-items of specific biblical failure on your part that exceeds your Grace Credit account holdings. And then Bam - hell forever, scumbag.
All the grace comes from God. Why are you questioning?
