This sermon, drawn from Psalm 98, calls God's people to live as a continuous act of praise, rooted in the redemptive work of Christ and extending to all of creation. It emphasizes that the 'new song' of worship is not merely a musical tradition but a joyful, heartfelt acknowledgment of God's salvation through Jesus Christ, the promised Messiah, whose covenant faithfulness and deliverance are the foundation of all true praise. The passage is interpreted as a call to the entire people of God—both Old and New Testament believers—to praise God sincerely, not only in song but in every aspect of life, as a lifestyle of glorifying Him. The sermon also distinguishes between the types and shadows of Old Testament worship and the transformed, Spirit-led worship of the New Testament, urging believers to be active witnesses in spreading the gospel so that all nations may one day join in joyful worship. Ultimately, the message is a passionate exhortation to live in anticipation of Christ's return, when all creation will finally glorify God in perfect harmony, and to actively participate in that coming kingdom by living and sharing the gospel with purpose and joy.
