Psalm 51:16-19 “Praying for Pure Worship on Zion”
Though much of Psalm 51 is a great example of how God's people should humbly turn from their sins and seek forgiveness (justification) and renewal (sanctification), there are also elements of the psalm that reflect David's unique position as King of Israel. After committing such horrible sins, he was concerned that, like his predecessor Saul, his lineage would be removed from the throne. This would have disastrous consequences, since David's son was destined to establish God's mountain upon the earth - Mount Zion (cf. 2 Sam. 7). David, therefore, prays that God would still build His city and confirm his royal lineage, so that a righteous Son of David might finally lead God's people in pure worship. By concluding with temple worship (Pss 65-68) and Solomon on the throne (Ps 72), Book 2 of the Psalter teaches God's people to expect a King like Solomon - one who would rule with wisdom at God's right hand, build Zion's walls and its temple, and offer up sacrifices in a way never seen before. When our Lord Jesus walked onto the scene, he uttered these wonderful words: "one greater than Solomon is here."
