Worship is a way of gladly reflecting back to God the radiance of his worth. This cannot be done by mere acts of duty. It can be done only when spontaneous affections arise in the heart.
John PiperThe murders of Newtown are a warning to me - and you. Not a warning to see our schools as defenseless, but to see our souls as depraved. To see our need for a Savior. To humble ourselves in repentance for the God-diminishing bitterness of our hearts. To turn to Christ in desperate need, and to treasure his forgiveness, his transforming, and his friendship.
John Piper
