In Psalm 146, the psalmist invites us to praise the Lord with our whole being and for our whole life. We may be consumed by worries of various kinds, but if we have put our trust in Jesus Christ, we can have assurance that God will take care of us. Such wonderful news should certainly make us sing for joy.
In Psalm 72, David prays for his son Solomon, king of Israel - that God will give him perfect justice and righteousness, that God will give him a long life and flourishing kingdom, that his dominion will extend to the ends of the earth, that he will be known for his care of the poor and needy, and that he will be a blessing to the nations. While Solomon partially fulfilled Psalm 72, God's answer to David's prayer would be fulfilled in Jesus Christ, who "will reign over the house of Jacob forever," and of whose "kingdom there will be no end” (Luke 1:31-33). While we wait for Jesus to come again to fully and finally establish God's perfect kingdom on the earth, may we bear witness to and pray for Jesus' coming.
In Psalm 122, the psalmist urges Old Testament pilgrims to pray for the peace of Jerusalem because "the house of the Lord" (Psalm 122:9) was in the city. Since the church is "a dwelling place for God" (Ephesians 2:22), we should pray also for the peace of the church. And as we pray for the peace of Jerusalem and the peace of the church, may we long for the day when the new Jerusalem will come down out of heaven from God, and when the dwelling place of God will be with man forever. Only in Jesus Christ can such perfect peace be found.
Advent is a season that helps us wait for Christ's second coming while we wonder at His first coming. But for some, this is not the most wonderful time of the year. In Psalm 80, the people of Israel are crying out for God to restore them. This He would do by sending His Son, Jesus Christ, to save His people from their sins. We all experience the brokenness of living in a fallen world, but the hope is that God will one day awaken His might and come to save us - fully, finally, and forever - when He comes again in the Person of Jesus Christ.
