This passage is a commentary on Paul’s words in Galatians: “Thus the law had become our guardian until Christ, so that we could be declared righteous by faith” (3:24). God desires obedience (Psalm 40:6), but we continually disobey. The law reveals what we do wrong, and we stand guilty before God. The sacrificial system was a way to temporarily cover sin, but we need a permanent solution. Jesus Christ offered Himself as the perfect sacrifice for sin (Psalm 40:7-8), ascended to heaven, and we are waiting for His glorious return (where all His enemies will be defeated). His perfect sacrifice makes it possible for us to be forgiven, holy, and righteous!
Psalm 110 “Here is the LORD’s proclamation to my lord: ‘Sit down at my right hand until I make your enemies your footstool’ The LORD extends your dominion from Zion. Rule in the midst of your enemies. Your people willingly follow you when you go into battle. On the holy hills at sunrise the dew of your youth belongs to you. The LORD makes this promise on oath and will not revoke it: ‘You are an eternal priest after the pattern of Melchizedek.’ O LORD, at your right hand he strikes down kings in the day he unleashes his anger. He executes judgment against the nations. He fills the valleys with corpses; he shatters their heads over the vast battlefield. From the stream along the road he drinks; then he lifts up his head.“
