Every day we are in a battle against both the schemes of the devil to defeat us and our own human nature and lifestyle. If we allow these three things to penetrate us and run their course, our lives can literally be ruined. They are not uncommon and they affect us all to some degree. They are the destructive characteristics of anger, bitterness, and unforgiveness. The initial wound causes anger to form.
Anger is acceptable so long as no sin is done as a result.
Anger can be controlled and worked through, and by effective communication eliminated. The result of anger, many times, is bitterness. Over time a wound can become infected with bitterness, if it is not cleaned up and allowed to heal. If bitterness sets in, the next complication is unforgiveness. Unforgiveness can not only destroy physical relationships with those around us, but it can prevent eternal life.
