Using Psalm 96, the sermon emphasizes that worship isn't just a ritual but a heart posture towards God, characterized by constant praise for His deeds, nature, and future judgments. It underscores that God deserves our highest praise for His creation, salvation, and majesty. The speaker urges the congregation to continually express their admiration for God, akin to writing 5-star reviews, and to worship Him not just in song but through every aspect of their lives.
