1. Come, all you who are thirsty (1-7)
People are thirsty for meaning, reconciliation and satisfaction. Though we spend money and labor in our own way, trying to satisfy ourselves, we become more thirsty. In contrast, God has established a covenant by which all peoples of all nations may come to him through the gospel of Jesus, of whom David is a shadow. His way is free of cost. Those who seek the Lord, forsaking wicked ways find mercy and free pardon. The forgiveness of sins and new life in Christ are what we deeply need and what truly satisfies our thirsty souls.
2. God's ways are higher than ours (8-13)
Our ways and thoughts struggle to understand God's mercy on sinners, but his ways are beyond ours. Instead of depending on our ways, when we trust in one word of God by faith, God's word works mightily to transform our guilt and shame into joy and peace; thorns and briers become juniper and myrtle, all for the Lord's renown.
