Be pleasing to Him for Whom you are soldiers, Him from Whom you will receive your reward. None of you must be a deserter.
Let your baptism serve as a shield, faith as a helmet, love as a spear, endurance as full armor. Your works are your deposits so that you may receive the full sum due you.
–- St. Ignatius of Antioch
