What to do with bad thoughts.What you dwell on is a matter of choice. Thoughts can only become a realty when attention is given.Casting down imaginations,weighing them against principles of righteousness.
2 Corinthians 5-6
5Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
6And having in a readiness to revenge all disobedience, when your obedience is fulfilled.
