"Worship is the submission of all of our nature to God. It is the quickening of the 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—all this gathered up in adoration, the most selfless emotion of which our nature is capable."
The definition comes from the famed archbishop William Temple
"Take this rule: whatever weakens your reason, impairs the tenderness of your conscience, obscures your sense of God, or takes off your relish of spiritual things; in short, whatever increases the strength and authority of your body over your mind, that thing is sin to you, however innocent it may be in itself."
Susanna Wesley (Letter, June 8, 1725)
John Wesley's own working definition of sin (although he did write that all transgressions of divine will need God's forgiving grace): "A willful transgression of a known law of God"
