The verses of this psalm strike a note of familiarity with the reader and the reason for this is twofold. The themes of praise for God, membership in His flock and the ultimate truth of His enduring love are all present. Because the truths present are all encompassing, the words of the psalm have made their way into countless hymns, choruses and prayers.
Shout for joy to the Lord, all the earth.
Worship the Lord with gladness;
come before him with joyful songs.
Know that the Lord is God.
Placed in the cultural context of Israel, there are also theological lessons that take root in the subconscious. The Lord is God, not one among many, not capricious and prone to tantrum as the imaginary gods of those surrounding Israel. Knowing this truth and the truths about God make worship and the joy inherent second nature. Unlike the way in which one might approach an idol—hoping but never knowing—approaching the gates of the Shepherd comes with assurance.
For the Lord is good and his love endures forever;
His faithfulness continues through all generations.
Assurance despite any temporary travail or circumstance comes through knowing God. The psalmist doesn’t speak from book knowledge here, he writes from the heart of one who has searched both his personal history and that of the people of Israel, knowing the peaks and valleys. Knowledge brings level to these ups and downs. Knowledge reminds us that time belongs to God and that the contours may only soften over time. Knowledge reminds us that we can still be joyful in this truth.
Grace and peace to you.
