"…every shilling which you needlessly spend on your apparel, is, in effect, stolen from God and the poor. And how many precious opportunities of doing good have you defrauded yourself of! How often have you disabled yourself from doing good, by purchasing what you did not [need]… I pray consider this well. Perhaps you have not seen it in this light before.
"When you are laying out that money in costly apparel, which you could have otherwise spared for the poor, you thereby deprive them of what God; the proprietor of all, had lodged in your hands for their use. If so, what you put upon yourself, you are, in effect, tearing from the back of the naked; as the costly and delicate food which you eat, you are snatching from the mouth of the hungry. For mercy, for pity, for Christ's sake, for the honor of his gospel, stay your hand. Do not throw this money away. Do not lay out on nothing, yea, worse than nothing, what may clothe your poor, naked, shivering, fellow-creature!"
(The Works of John Wesley, vol. 7, "On Dress")
"You bind your own hands. You, make it impossible for you to do that good which otherwise you might. So that you injure the poor in the same proportion as you poison your own soul. You might have clothed the naked; but what was due to them, was thrown away on your own costly apparel. You might have fed the.hungry… but the superfluities of your own table swallowed up that whereby they should have been profited. And so this wasting of thy Lord's goods is an instance of complicated wickedness; since hereby thy poor brother perisheth, for whom Christ died."
(The Works of John Wesley, vol. 8, "A Farther Appeal to Men of Reason and Religion")
"If I leave behind me ten pounds (above my debts and my books or what may happen to be due on account of them), you and all mankind bear witness against me, that I lived and died a thief and a robber."
(The Works of John Wesley, vol. 11, "An Earnest Appeal to Men of Reason and Religion")
