Flash, by example and by definition, I have concluded that sin and imperfection are NOT the same. Sin is worse, because it is a willful choice. For instance , a child can make a bed imperfectly, but the act is not sinful. That same child, having a screaming tantrum in the middle of the bedroom floor because HE DOES NOT WANT to make the bed, is far worse than imperfect. It is willfull rebellion.
We are in agreement. Unless the childs parents laid a law on the child for his bed to be made 'perfect' no sin is made. The differance is in our ability to consistantly choose at all levals in all areas to live by law or not. As it is now, we cannot by nature, flawlessly adhere to law, God's or man's. If I were perfect and were learning to play the piano, I, because of my inexperaince will make mistakes in playing the music. I will be for a time, un-skilled and my playing will be imperfect.
