FULGENTIUS OF RUSPE:
We defeat the adversary only if we fight with tears and with prayers, in continual humility of heart. It is written, in fact, that “the prayer of the humble penetrates the clouds and is not withdrawn from God until it is answered.” The weeping of the humble is therefore a great antidote against carnal concupiscence. Tears that spring from compunction of heart defeat the enemy and gain for us the gift of a victorious happiness. In fact, those who “go out weeping, scattering their seeds, will return rejoicing, carrying their sheaves.” How wisely the holy prophet teaches that the seeds of good works must be watered with rivers of tears! Indeed, no seed germinates without being watered. Nor does a seed bear fruit if it has been without the benefit of water. We also, therefore, if we wish to harvest the fruits of our seeds, should not cease watering them with tears, which should spring from the heart more than from the body. This is why we are told through the prophet to rend our hearts, not our garments.
