The praise songs of the late 1970s and early 1980s, to their credit, often did have richness that few present-day songs match. That richness came because many of those songs, despite being simple and repetitious, drew their lyrics directly from Scripture (usually the Psalms).
John Michael Talbot popularized Psalm 57:9-11 in his beautiful praise song, Be Exalted, O God. Not only is it pleasurable to sing, but it gently redirects attention from ourselves to the Lord. The psalmist seeks after the Lord to glorify Himself.
The song always gave me proper perspective. God’s job isn’t to give me purpose, to have a wonderful plan for my life or to bless me with good health and material prosperity. He exists for the sole purpose of glorifying Himself. Thankfully, He often demonstrates His glory through His love and faithfulness to me, causing me to praise Him publicly. As you listen to the psalmist’s prayer, won’t you join him (and join me) in asking the Lord to let His glory be over all of the earth?
