James 5:16

Confess your trespasses to one another, and pray for one another, that you may be healed.  The effective, fervent prayer of a righteous man avails much.  

Have you ever noticed that the devil has an easier time condemning us with secrets than he does when we confess our faults?  Suddenly, our problem decreases in size because we no longer let it control us and we take control over it with the help of God.  Confessing our faults releases healing into our lives.  When we pray in faith to God, we receive answers and help in our lives.
