I know Barth is not really accepted by fundamentalists or liberals(for good reason), but I remember stumbling across a quote by him that was phenomenal. He proposed that all of our various sins stem from specific three sins. I remember one of the sins was slothfullness, and I think another one was the desire of acceptance from man or fear of man. If someone knows the other sin, I would be grateful. So far, from my own life, I can agree with his thesis. Sloth has done more dammage to my spiritual walk then anything else. Acceptance of peers has caused me to not evangelize in a bold, God honoring way. I'm anxious to find what the third sin was.
