"Give the king your justice, O God, and your righteousness to a king's son." (Psalm 72:1)
The traditional understanding is that the king in question is Solomon. Yet, Psalm 72 continued to be used after the disappearance of the monarchy. According to The New Interpreter's Bible Commentary, "Verse 1 clearly marks the beginning of Psalm 72 as a prayer, and it introduces the two key words and concepts: justice and righteousness." The words "justice" and "righteousness" are not simply for the earthly king to determine. These fundamental words define how the king is to live out God's royal policy.
Both "justice" and "righteousness" are not words used to honor the king. "Justice" and "righteousness" focus on the poor and those in need. Hence, the role of the king is to be God's representative in caring for the poor and needy. To be a "ruler" is not about self-aggrandizement, but about caring for the daily and long-term needs of the poor and needy.
Pray for our political leaders today, and pray for our presidential candidates as well. Then, pray for America's citizenry, that we will seek a President and other political leaders who will focus less on their own ego and more on the needs of our poor and needy. We are only as strong as the weakest among us. The Psalms do not focus on heaven, at the expense of our earth. For the Psalms, our world, and all the human beings in it, are valued. We live not simply to get our ticket punched for heaven, but to make a difference in this world that God cares so much to restore.
