Sin affects men in various ways, but it attacks them in every facet of life. It hinders their walk with God and hurts their ability to reach others for Christ.
It is imperative that each believer not only do what is right, but also examine himself to make sure that he is doing what is right for the right reasons.
It is always right to do right, but it is more perfectly right to do right for the right reasons. In other words, serve the Lord, but do so out of a pure motive.
