David opens this psalm with an admonition to praise and rejoice in the Lord, suggesting playing the harp and other instruments, singing joyfully. He then extols the greatness of God’s word. His word is right, true, and full of justice and goodness. By His word the heavens and all the hosts of the earth were made, and He gathers the waters in storage. All the earth should fear the Lord and be in awe of Him. The Lord stymies the plans of the nations, but His counsel stands forever. Blessed is the nation whose God is the Lord! God can see all His creation from heaven. Kings are not saved by their might or their horses, but the eye of the Lord is on those who fear Him, to deliver them. He sums up the psalm with this:
20 Our soul waits for the Lord;
He is our help and our shield.
21 For our heart shall rejoice in Him,
Because we have trusted in His holy name.
22 Let Your mercy, O Lord, be upon us,
Just as we hope in You.
David’s heart loves to praise God. In this case, He speaks of God’s creative power, His saving power, His power in battle, His power to deliver. David shows that the Lord is a sovereign force in heaven who effects life on earth. God is the Lord over all, and He blesses those who trust in Him. Trust in the Lord and give Him praise!
