The central message of this sermon is that praising God is not only commanded but also essential for human beings, as it allows us to recognize and value God as the source of all true worth and significance. By praising God, we are essentially "tuning ourselves" to His ultimate truth, enabling us to properly value and prioritize things in our lives. This praise is not necessary because God needs it, but rather because we need it - we need encouragement, help, and people who are pulling for us. Through the act of praising God, we remind ourselves of His character, benefits, and perfection, which in turn enables us to put things into proper perspective and make value judgments that align with God's truth. Ultimately, this sermon emphasizes the importance of praise as a means of spiritual calibration, enabling us to live out our daily lives in accordance with God's will and values.
