At Elder meeting last night I shared from Allender & Longman's book, The Cry of the Soul: How our emotions reveal our deepest questions about God. Navpress ISBN1-576683-180-9. I focused on chapter 15: "The Redemptive Power of Divine Shame". I believe that it contains some essential concepts for defeating the illicit power of shame in our lives. The text says, "Shame leads to self-absorption, hiding, and hateful contempt [and it is] an exposure of our idolatry". How does shame point to our idolatry? Because when we feel shame, it is usually due to our fear of others' judgments of us and we don't trust them to handle our secrets. Yet, "God chose the weak things of the world to shame the strong." Our ability to overcome the world is not found in our strengths, but in God using our weaknesses. "We are to shame the world by reveling in the beauty of weakness. Here is the paradoxical ground where God's strength is revealed: we are to rejoice in foolishness, because through it God's wisdom shames the wise." It is surely foolish to reveal our shame, our secrets, our sins to one another. The world is terrified of being shamed or embarrassed. It is not cool. However, "God invites us to bear disgrace in order to befuddle a world terrified of shame."
This lesson has particular application in light of Pastor Brett's admonishment to make grace, rather than trust, the baseline of our relationships with each other. If we extend grace to one another, even though we know we will be hurt, embarrassed, even shamed, then we can be authentic and honest without conditions and without fear.
My favorite author, Fred Rogers, got it almost right:

“Anything that’s human is mentionable, and anything that is mentionable can be more manageable. When we can talk about our feelings, they become less overwhelming, less upsetting, and less scary. The people we trust with that important talk can help us know that we are not alone.”
I'd submit that it is the people we 'grace' with that important talk who can help us know that we are not alone. When they prove untrustworthy, we rejoice that God is completely trustworthy and he chooses to use us, even with our shame, for his glory.
