We come this morning to an Imprecatory Psalm; a psalm in which the author calls on God to judge his enemies. Within Psalm 139, righteous anger is modeled for us. Clearly there is a right way to be angry and a wrong way to be angry, a sinful way. And this text helps us learn the right way to be angry. If our anger is to be righteous it must be God-centered, primarily focused on God's concerns and glory.
