As an Evangelical, I don't participate in formal confessions as in the Catholic churches, but an integral part of every Christian's life is the discipline of confessing our sins to one another. Last night at small group, we broke into guys and gals and confessed to each other some besetting sins that we consistently struggle with, and then as a group, talked about how the truth of the gospel informed each of those situations.
It can be so hard to share, because we all know that the rest of the group is made up of people with problems - it's hard to face potential judgement or criticism or holier-than-thou attitudes. But when God is moving, the encouragement is so, so worth it. Praying for each other, and helping each other through the difficulties - it so helps me to walk in victory and to celebrate the power of God over Satan.
So yeah, being a Christian is pretty dog-gone awesome. :D
