What does Psalm 145 teach about the role of singing in worship?

In this psalm, verse 7 indicates that 'they shall sing of thy righteousness.' Singing is not only an expression of praise but a powerful way to teach and affirm theological truths about God. Through hymns and psalms, worshippers affirm God's righteousness, reflecting on what He has accomplished for them in salvation. In the New Testament, Paul instructs believers to teach and admonish one another through psalms, hymns, and spiritual songs. This continuity from Old to New Testament shows the importance of music in worship as a tool to reinforce faith and community identity. Therefore, singing becomes central to declaring God’s attributes and works, helping to instill His truth in people's hearts across generations.
