Murder, we have

No sane person  would actually admit to committing murder. Of course not! It's inhumane, it's illegal, and it's downright ugly. But I want to talk about a different kind of murder. When we sin, we murder. We murder ourselves with lies that we aren't good enough for God to love. We murder each other with our words, our actions, and our greed. We even murder our bodies into starvation, exhaustion, impatience, and thought. So my question is- how do we stop murder and start living?
