Our responsive reading today is from Psalm 148 which tells us that the goal of all of creation is to join in the worship of the one, true living God. All things are moving toward that eternal destiny.
Paul tells us that there will be a day when every knee will bow and every tongue confess that "Jesus is Lord" to the glory of God the Father (Phil 2:5-11). The great, heavenly visions of The Revelation show us the saints gathered before God's throne offering their praises to Him. This fulfillment of their salvation, as they worship the God who is both Creator and Redeemer, will also include the creation of a new heaven and a new earth. They will both be united again, as they were before Satan's revolt and our earthly fall, in the praise of God.
This psalm anticipates the great, end-times consummation of all things. It reveals heaven and earth joined together in worship. Verses 1-6 call for the heavens to praise the Lord. Verses 7-12 call for nature and the nations to praise the Lord. All things are to join in this praise, especially His chosen people (verses 13-14).
