Wm. Temple:

Worship is the submission of all our nature to God. It is the quickening of conscience by his holiness; the nourishment of mind with his truth; the purifying of imagination by his beauty; the opening of the heart to his love; the surrender of will to his purpose--and all this gathered up in adoration, the most selfless emotion of which our nature is capable and therefore the chief remedy for that self-centeredness which is our original sin and the source of all actual sin.
