Do not then mar thy labors, nor cast away from thee the fruits of thy toils, neither run thou in vain, making frustrate all thy labor after the many courses thou hast run. Nay, for thy Lord knows thy good works better than thou dost. Though thou give but a cup of cold water, not even this doth He overlook; though thou contribute but a farthing, though thou shouldest utter a sigh only, He receives it all with great favor and is mindful thereof, and assigns for it great rewards.
