“The king shall have joy in Your strength, O Lord; and in Your salvation how greatly shall he rejoice! You have given him his heart’s desire, and have not withheld the request of his lips.” Psalms 21:1-2
We know that David wrote psalms over the course of his whole life. With most of his psalms it’s really impossible to tell, even generally, when he composed them. Psalm 21 is, in my opinion, one of those where we can at least have a general idea as to when he wrote it. I believe that this psalm was written during the years when David was serving in the court of king Saul.
Saul was blessed by David’s service to him, his music soothed the tormenting spirit and his achievements as a warrior brought stability and honor to his kingdom and his throne.
It’s clear that David was reluctant to in anyway undermine Saul’s position as leader in Israel. David’s actions toward Saul, all through his life, show nothing but respect, compassion, and love. Even during times when Saul would have happily killed him.
In Psalm 21 David celebrates God’s care for a man that God has already rejected and replaced. God has distanced himself from Saul to such an extent that an evil spirit is able to torment him and yet David sees that in during this time there is still evidence that God cares, and is, in fact, caring, for Saul.
In Psalm 136 David celebrates the enduring nature of God’s love and mercy toward us by repeated intoning the phrase, “For his mercy endures forever.”
Our disobedience, our rebellion, our blasphemies, and our plotting against God cannot extinguish his love for us or stop him from raining his mercies down upon us. Even in his anger, when he is compelled to move against us in judgment and punishment, his actions still reveal his mercy and his goodness.
I believe that that when all is said and done heaven’s record books will reveal that God’s love and mercy for the lost compelled him to strive for their salvation long after all chance of their accepting him had past.
Why would he do that?
Because he loves. The apostle John tells us that God is love. And his love endures forever.
