Can you catch sin like a cold? – Barnabas Piper: "So many Christians live in cultural quarantine, shutting themselves off from what they see as sinful influences. They avoid 'bad' people and even places. They talk about those people and places like they are disease carriers – 'We can't have them around' or 'We couldn't go there.' They act like someone can sneeze sin onto them, that they will catch the bad decisions and guilt of another through physical proximity. What does his shunning communicate to those we have labeled 'unclean'? Exactly that, Christians think they are unclean. Not the ideal way to draw people to Jesus. But sin is not an infectious disease."
