This sermon began last week when I was trying to explain to someone that we do not add coldness to something. We can remove heat from things like we can remove light from a dark room. We can remove everything from a cylinder and have a vacuum. But we can't add a vacuum. I was soon arguing my point and never convinced my adversary that coldness is not a quality but the absence of a quality, heat.
Some people think sin and grace are like that.
Sin is not added. When a baby is new born, the baby is without love for others, even its mother. The love has to be added. Initially, a baby is a marvelous gastrointestinal tract. Those who love the baby feed one end and clean up the other.
