Psalm 86

The end of psalm 86 is a call for something more tangible than the peaces that surpasses understanding. And I wonder what are the circumstances in which God demonstrates his favor with physical demonstrations? David asked for mercy, strength, deliverance, and then he asks for evidence of God's favor. But this was not evidence only the David the oppressed believer, it was evidence that the oppressors would see. Since David expected those oppressing him to be ashamed it would make sense that his persecution was coming from those inside the faith.
