Original sin is an important doctrine that points out, among other things, that we are not quite right. As St. Paul says, “I can will what is right, but I cannot do it. For I do not do the good I want, but the evil I do not want is what I do” (Romans 7:8-9). Our passions are at war within us. This is our own fault, not God’s. It indicates something broken within us, which all the therapy and perfect upbringing in the world cannot fix. Only God’s grace can heal this wound.
