Summary: David sees injustice caused by wicked men all around, while God seemingly looks the other way. He pleads with God not to let them go unpunished.
Response: Now this is a primal urge I can get behind. Man injustice is rampant today. The way our ways of life are set up are designed to take advantage of one another. That's not how God designed us to live! Lord, help me be part of that change, part of that justice; help me to take that first small step.
