"And men will say, “Surely there is a reward for the righteous; Surely there is a God who judges on earth!” (v.11)
This Psalm was written against wicked rulers. It has been suggested that it was penned because, Abner and the rest of Saul's princes, who judged David as a rebel and outlaw, urged Saul to pursue him. The psalm is laid out in three parts: a description of the evils of the unrighteous judges (vv.1-5); prayer for their overthrow (vv.6-8); the ultimate realization of the triumph of righteousness (vv. 9-11).
We too at times may feel that unrighteous rulers are chipping away at our lives as well. Whether they are judges, politicians, lawyers, or ones boss, I’m sure you (like David), have prayed against unrighteousness in some area of your life, and even cried out to God for justice. But as Christians, we are also called to love. And therefore, we should also to pray against the forces that bind the unrighteous. Then, as David did, rest in the knowledge that righteousness will eventually triumph.
But, until then as Jesus said, "Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you” (Luke 6:28). Remember, if it were not for God's mercy, and long-suffering we would have been found wanting a long time ago. Therefore, be patient, pray for His will in every situation, and leave judgement to God. It will happen, but in His timing.
The Truth: "From his mouth came a sharp sword to strike down the nations. He will rule them with an iron rod. He will release the fierce wrath of God, the Almighty, like juice flowing from a winepress.” (Revelation 19:15)
