This passage explicitly describes King David, but it is clearly a type of Jesus Christ.
David’s great passion for God foreshadowed the heart of Jesus. We see David’s enthusiasm for God in every phase of his life. He was devoted to God as a shepherd boy, fending off lions and bears to protect his father’s flock. He was devoted to God as soldier, slaying Goliath with a minimum of weaponry and a maximum of courage. He was devoted to God as a king, putting Israel on the map with military victories and wise alliances. He was devoted to God as a poet and musician, being the major figure behind the book of Psalms. He was devoted to God as a benefactor, enabling Solomon to reign in unparalleled glory and peace. But David was just a foreshadowing of Jesus, whose devotion greatly exceeded David’s.
We see Jesus as the person who is the ultimate fulfillment of these words: “A man after My own heart, who will do all My will.” He who knew no sin was made to die on a cross for our sins, yet while suffering He uttered no threats and while being reviled He did not revile in return. He didn’t surpass David’s example, however, that we might merely admire Him. He did so that we might imitate Him.
As Jesus inspired this accolade from His Father (in typified form), let us see what kind of accolade our behavior might elicit from Jesus. Oh, thanks be to God and praise be to God for His awe-inspiring example to us!
