What a reproach it is to the profession of the gospel to see a Christian just come from church and holy ordinances where his devout affections have been raised, and immediately to find him breaking out in vain, earthly merriment and carried away with idle and sensual discourse.
And again:
Whenever you find a tempting creature taking too fast a hold of your passions, set a guard of sacred jealousy upon it, keep your heart at a holy distance from that creature, lest it twine about your inward powers, and draw them off from their allegiance and duty to God your creator.
Isaac Watts, The Love of God
