How to keep from sinning

Since one of our first needs as humans is to be thought blameless, here are two ways to keep sin at bay.

If you are a conservative, I would suggest putting your focus on individual sins. Rank them. Make sure you hold the worst sins in absolute disdain. Naturally, these will be the sins you would never think to commit yourself, and, helpfully, you have no trouble avoiding. If you can keep away from them, why can't everyone else?
Now that you have identified the worst sins, and these are clear to all, whatever sin you had disappears. After all, you are not a murderer, are you? Compared to them, you're blameless. Tada! Sin's gone!

If you are a liberal, you might try the ills of society route. Put all sins in the context of 'we.' Our society does a lot of really bad stuff, like wars, oppression, and so on. Don't forget the ones that were committed centuries ago. Then place yourself above all that. "We" always means other people. Since you identified the problem, and you are the prophetic voice against it, once again, you cannot be blamed.

Isn't denial wonderful? So simple, it's just a matter of pointing out the sins of others.

If neither of these routes suits you, then go into your room and shut the door; kneel down and pray like this: "Lord, be merciful to me, a sinner."
The only alternative to self-justification is divine mercy.
