After reading this verse, one must ask, ‘who is really the person being spoke about in this Psalm?’ Although this Psalm is authored by David and is speaking of his desire to do the right thing, there is something farther reaching in these words.
I have yet to see a leader in human history live up to the standards set in this coronation speech. Therefore, it seems this Psalm ties to Jesus Himself being the ultimate ruler who will fulfill what this Psalm teaches.
This Psalm is not just teaching us what was David's standard for being a good leader. It is about understanding what is God’s standard when Jesus comes to rule over this world one day. This words should be our leader’s standards as well.
This verse says that whoever is speaking will be among the faithful in the land. David can only judge actions and not read people’s minds. As a leader, David had to judge how people act and see if they are faithful to him and faithful to God’s desires for their lives and all of our lives. David’s point seems to be that he wants faithful people to be around him to do the right thing as servants of God and do God's will through their lives.
Practically, Christ is the ultimate ruler over our lives. All of us live in a world and we have to deal with imperfect people who are over us. At the same time, we as Christians should recognize God as the ultimate authority over our lives. This may be a delicate balance in our lives at times to do what our leaders over us tell us to do but not violating biblical principals.
There are a handful of stories in the Bible where someone tells their appointed leaders they cannot do what their leaders ask of them. Sometimes such people have to suffer in this lifetime for taking such a stand for what is right. Remember, God will eventually reward us when we take such a stand to do the right thing.
One example we read about in Exodus is a time when the leader of Egypt ordered women in charge of delivering babies (“midwives”) to kill the Jewish babies as they were being born. Those Egyptian women lied to their leaders and didn’t kill the babies. The story mentions that God blessed those midwives for doing the right thing and gave them their own families (see Exodus 1:15-20).
The point of verse 6 is that God calls on us to do the right things in life and that He desires our leaders to appoint people under them who also are to do what is right in life. Sometimes doing the right thing takes “guts” but we must not fail to remember that taking a stand for doing the right thing will always make us victorious in the long run.
