"Every Christian, as soon as he is baptized, is marshaled into an army in confrontation with the devil. And from his baptism onwards, is saddled with the devil, who harasses him as long as he lives. If this bitter enemy cannot by his onslaughts get the better of Christians and bring about their downfall, he seeks to hang them on the cross and kill them, as he did Christ. All Christians face such attack. For the adversary never relents, but continues to try to wrench us away from Christ and our baptism. By means of hunger or persecution, by worldly fame and wealth, or by heresy or false interpretation of scripture. So that we give way either to despair or vainglory." —Martin Luther Invacovit Sunday Sermon 1534
