Confess your sins to each other and pray for each other so that you may be healed. The earnest prayer of a righteous person has great power and produces wonderful results. (James 5:16 NLT)
In Christ centered community, confessing our sins to one another is a real function that helps draw us closer together.
I can honestly say that Christ centered community is often overlooked my the typical married couple. If you are married or are engaged to be married, confessing your sins to your spouse can be one of the most liberating things you do with one another. It has made my bond with my wife much stronger and our relationship better.
The truth does set us all free.
