When I opened my computer I found emails sent to a friend but somehow also sent to me. I inquired as to the reason and was told that a hacker had got into his computer address book and was spewing out messages to all his correspondents. Fortunately it didn’t result in giving my computer a virus. But not so with mankind: the infection of sin, like a computer virus, has warped human nature so that it erupts in selfishness and greed.
