1 Chronicles 16:23-24 Sing unto the Lord, all the earth; shew forth from day to day his salvation. Declare his glory among the heathen; his marvelous works among all nations.
After David brought the Ark to its resting place, he led the people in raucous celebration, and he penned this Psalm. Here he calls for a celebratory response from all the earth. The Lord has come; everyone and everything on earth should be so excited they will sing to the Lord; they will show the world God’s salvation every day of their new life; and they will declare the glory of God and His marvelous works to the heathen nations that do not yet know how good and how great God is. This great and good God is now here among us in our hearts.
”The heavens declare the glory of God and the firmament shows His handiwork.” And all the created things wait for the revealing of the sons of God (the Second Coming). And the human believers articulate the gospel to the nations that have not yet heard and believed. Along with singing, worship, and preaching, the human believers respond by living a life that gives glory to God. The world’s people hear, believe, and are saved. “Joy to the world, the Lord has come.”
