Some Thoughts On Worship from Piper - Desiring God

"Worship is a way of gladly reflecting back to God the radiance of His worth."

"Where feelings for God are dead, worship is dead."

"Worship is authentic when affections for God arise in the heart as an end in themselves."

"The real duty of worship is not the outward duty to say or do the liturgy. It is the inward duty, the command "Delight yourself in the Lord!" (Ps. 37:4). "Be glad in the Lord, and rejoice!" (Ps. 32:11)

"Don't let your worship decline to the performance of mere duty."

"The irony of our human condition is that God has put us within sight of the Himalayas of His glory in Jesus Christ, but we have chosen to pull down the shades of our chalet and show slides of Buck Hill - even in church!"

I have nothing to add. Some sobering thoughts to think about!
