Suddenly, everything changes. You find yourself averting that person. You find yourself avoiding places where you might bump into them and avoiding people who they might be with. It is due to your broken relationship. The same dynamic occurs in what we call sin.
Sin is more than the details or the individual act.
Sin is in the big picture, in the attitude. Sin is the brokenness of our relationship with God. We who are Christians look back on our lives and see it clearly. Before we had our relationship with God restored, we recognized there was something wrong, but we were unsure what it was. We had a lot of criticisms of life as it is, but no real solutions for ourselves.
