But alway take heed that thou fight with this mind and hope, as though that should be the last fight that ever thou shalt have, if thou get the over hand: for it may be verily that the benignity of God will give and grant this reward unto thy virtue and noble act: that thine enemy once overcome to his shame, shall never afterward come upon thee again. A thing which we read to have happened to divers holy men: neither believeth Origene against reason, that when christian men overcome, then is the power of their enemies minished, whiles the adversary once put back manfully is never suffered to return again to make a fresh battle. Be bold therefore in the conflict, to hope for perpetual peace. But again after thou hast overcome, so behave thyself as though thou shouldest go again to fight straightway, for after one temptation, we must look ever for another: we may never depart from our harness and weapons: we may never forsake our standing: we may never leave off watch as long as we war in the garrison of this body. Every man must have alway that saying of the prophet in his heart, I will keep my standing.
