“God is worthy of our highest, purest, and strongest emotions. Singing helps express and unite them. Singing without emotion is an oxymoron. Vibrant singing enables us to connect truth about God with passion for that truth.” - Bob Kauflin
"And the duty of singing praises to God seems to be appointed wholly to excite and express religious affections. No other reason can be assigned why we should express ourselves to God in verse, rather than in prose, and do it with music but only, that such is our nature and frame, that these things have a tendency to move our affections." - Jonathan Edwards, Religious Affections
