Psalm 13 is often overlooked. It's not even in the lectionary. But this short Psalm has a powerful message about the importance of lament and hope.
Lament is needed in order to honestly name the things that bring us harm. Pain that isn't named, cannot be healed. Injustice that isn't named, cannot be addressed. Fear that isn't named, cannot be confronted. Etc. Therefore, lament is an important part of naming the things that need to be named so that life-giving change can occur. And that change - the change we desire and God envisions - is what gives us hope for the future.
We thought that Psalm 13 needed to get dusted off and held up as a vision for the "Mainline" Church at this time of transition. Difficult things need to be named and addressed so that hope for a better future can be claimed with boldness.
