Psalm 108 teaches that steadfast worship begins with confidence in the unchanging character of God. Although David originally wrote these words during times of danger and conflict, he declares that his heart is steadfast because God's steadfast love and holiness never fail.
This sermon follows the psalm's progression from praise to prayer, showing how God's faithfulness gives His people confidence in every circumstance. Ultimately, Psalm 108 points to Jesus Christ, whose victory over sin and death calls believers to remain steadfast in worship, obedience, and the work of the Lord.
