Sin demands atonement. Atonement puts God and man at one. When atonement is made man is cleansed and forgiven. In other words, things are made right.
Sin is not to be considered a light matter. In other words, it is not to be mocked. Only a fool would demonstrate this kind of behaviour toward sin.
Sin and those who participate therein anger Lord. In the days of Noah, sin grieved the Lord so badly that it repented God that he had made man on the earth.
The Bible does not always paint man in a positive light, yet it always paints him accurately. According to scripture, there is no man that sinneth not.
