The third installment in this sermon series looks at worship through the lens of song. Why are songs/hymns selected for worship? What should be our expression as we sing? What instrument should we play or not? And is this as big a deal as people make it out to be? Are we required to sing with joy? Psalm 71:22-24 bring our focus back to the principle of worship in song and that is to glorify God as we sing. With that in focus we look to Psalm 71.
