"Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective." James 5:16

I think this verse means that you should be able to acknowledge your sins to others so they can help you heal. Confessing your sins is a step toward repentance so if you are able to confess to a family member, or friend..(etc) they might be able to pray for you. When you are trying to heal from your sins, prayers from others can help by lifting a weight off your shoulders by just knowing that they're praying with you.
