You reap what you sow.

This is quite a karmic way of looking at "Ya got what was comin' to ya." Though it's tough to imagine some Italian mobster actually saying, "You reap what you sow," it is true. Bad things end up happening to bad people, and good to good, and sometimes they get confused, but end up straightening out at some point. Not necessarily with expedience, but in general I'd say this is true, especially if you adhere to the Heaven/Hell Afterlife dynamic.

One thing that bothers me about believing in an afterlife is the concept that Heaven is a reward, something to be worked toward. And while it's not explicitly stated that Heaven's a reward, it's implicit. It's essentially seen as a grown up version of getting a lollypop if you're a good girl and sit still during mass. I don't think this is necessarily what is meant to be taken away from a Christian worldview (or any other religious order for that matter), but it bothers me that it's become this way. The fear of hell shouldn't be what makes you stay within the lines. The joy found in kindness, laughter, friendship, loyalty, honesty, generosity, love, passion, humor, touch, and all things good is what should keep you good. If you really think about it, most everything else ends up savoring of bitterness. Then again, what is good, anyway?

Unrelated Question: The Grim Reaper. We all know him. He essentially "reaps" bad people. So, is he the ultimate bad guy?

Another note: I love the phrase "Sewing wild oats." At the end of my life I'd like to see what's reaped from those.
