A simple psychological principal is that telling ourselves or other to "Don't" is less effective than telling them to "Do" something else. "Don't hit the ball in the water" is a common golfer mistake. "Keep your head down and follow through" is more productive. Focus should be on what we should do and not on what we should avoid doing. The same is true in our spiritual life. We should focus our attention on the right things to do and avoid focusing on the "don'ts".
Lord, help me to submit to You and to resist evil.
