Matthew Henry Commentary Psalms 72:18-20

"Blessed be Jehovah God, the God of Israel, Who only doeth wondrous things: And blessed be his glorious name for ever; And let the whole earth be filled with his glory. Amen, and Amen. The prayers of David the son of Jesse are ended. BOOK III" — Psalms 72:18-20 (ASV)

We are taught to bless God in Christ, for all he has done for us by him. David is earnest in prayer for the fulfilment of this prophecy and promise. It is sad to think how empty the earth is of the glory of God, how little service and honour he has from a world to which he is so bountiful. May we, like David, submit to Christ's authority, and partake of his righteousness and peace. May we bless him for the wonders of redeeming love. May we spend our days, and end our lives, praying for the spread of his gospel.
