Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective . Though we aren't a church, we have the type of fellowship that allows for vulnerability, that allows for those that are hurting to find prayer and healing. As I've recognized in my own walk, it's when I'm the most caught in the snare of my own sin that I hurt the most. Yes, we also pray for the healing of the sick in our midst, but it strikes me that we sometimes hide the things that we need prayer for the most.
Confession is good for the soul.
It works in the surrender of your weakness in the presence of God or other believers. It works because as you are healed, your testimony of God's healing through prayer is one that glorifies Him. So just begin. It doesn't really matter if your prayer is formal or casual, heart-wrenching pain or a praise of thanksgiving. God'll take it.
