One of the more neglected tools that can help us grow in our holiness is the confession of sins one to another (James 5:16). It can be difficult to admit to other people that we have sinned, but loving brothers and sisters in Christ can help assure us of His forgiveness and help us overcome persistent temptations. Without being involved in the lives of other believers we will not find these opportunities. Take the initiative and be a part of the lives of other Christians.
