That may yet be called a truly christian life that is never at perfect rest, and has not so far attained as to feel no sin, provided that sin be felt, indeed, but not favored. Thus we are to fast, pray, labor, to subdue and suppress lust. So that you are not to imagine that you are to become such a saint as these fools speak of. While flesh and blood continue, so long sin remains; wherefore it is ever to be struggled against. Whoever has not learned this by his own experience, must not boast that he is a Christian. Hitherto we have been taught, that when we made confession, or joined ourselves to some spiritual institution, we were at once pure and needed no longer to contend with sin. They have said, moreover, that baptism purifies and makes holy, so that nothing evil remains in the person. Then they have thought, "now will I have a pleasing rest," but the devil has come and assaulted them worse than before. Therefore understand the thing well, though you confess and permit yourselves to receive absolution, you must do even as the soldier, who in battle runs upon the points (of the javelins); whenever the critical moment approaches, and the conflict rages, compelling him to strike right bravely, as if to repel outrage, then he must draw out his sword and lay about him; but while the strife threatens only, so long must there be untiring vigilance. So, although you have been baptized, be on your guard, inasmuch as you are not safe for an hour from the devil and from sin, even though you think you will have no more assaults. Therefore a christian life is nothing else but a conflict and encampment, as the Scripture says; and therefore the Lord our God is called the Lord of Sabaoth,--that is, a Lord over the hosts. So also, _Dominus potens in praelio_--the Lord mighty in battle. And thereby He shows how powerful He is, that He permits His people to be exposed in the conflict and rush upon the points (of the javelins). Yet so that while the trumpets are ever sounding He is ever observant, (saying) beware here, beware there; thrust here, strike there. Besides, it is a lasting conflict, in which you are to do all that you can, so that you may strike down the devil by the word of God. We must therefore ever make resistance, and call on God for help, and despond of all human powers.--Now follows further:
