The second section of the book of Psalms (chs. 42–72) ends with the entire earth blessing God forever! Unending universal praise is proper for the One who alone does wondrous things! This psalm describes an ideal kingly rule which, to some degree, characterized the early years of Solomon’s reign.
The description of the king’s rule by the psalmist is a description of God’s rule, “who only does wondrous things” (Ps. 72:18). The God of Israel alone is the God who judges righteously, brings peace to His people and justice to the poor. He alone delivers the needy when they cry and redeems them from oppression. Indeed, all “shall be blessed in Him; all nations shall call Him blessed” (Ps. 72:17).
Such a benevolent reign is most fully reflected in God’s Son, the Messiah of King David’s line. Jesus alone perfectly carries out the will of God. All who come under His righteous rule begin to enjoy the blessings of God’s kingdom. With the psalmist, we cry out “let the whole earth be filled with His glory. Amen and amen.”
