In "God's Word for Today" David Woods writes:
Too often we do conduct our worship services without purpose. Mindlessly singing songs we’ve sung for years, we blindly follow patterns established years before.
**Discussion: **Why do we sing praise to God? What is our purpose in worship? Is singing praise songs about me and my feelings?
David encouraged us to approach worship more thoughtfully and purposefully in the introductory verses of this Psalm.
