Now, since no one lives on earth upon whom God does not bestow an enemy and opponent as a proof of his own anger and wickedness, that is, one who afflicts him in goods, honor, body or friends, and thereby tries whether anger is still present, whether he can be well-disposed toward his enemy, speak well of him, do good to him, and not intend any evil against him; let him come forward who asks what he shall do that he may do good works, please God and be saved. Let him set his enemy before him, keep him constantly before the eyes of his heart, as an exercise whereby he may curb his spirit and train his heart to think kindly of his enemy, wish him well, care for him and pray for him; and then, when opportunity offers, speak well of him and do good to him.
Let him who will, try this and if he find not enough to do all his life long, he may convict me of lying, and say that my contention was wrong. But if this is what God desires, and if He will be paid in no other coin, of what avail is it, that we busy ourselves with other great works which are not commanded, and neglect this? Therefore God says, Matthew v, "I say unto you, that whosoever is angry with his neighbor, is in danger of the judgment; but whosoever shall say to his brother, Thou fool (that is, all manner of invective, cursing, reviling, slandering), he shall be in danger of everlasting fire." What remains then for the outward act, striking, wounding, killing, injuring, etc., if the thoughts and words of anger are so severely condemned?
III. But where there is true meekness, there the heart is pained at every evil which happens to one's enemy. And these are the true children and heirs of God and brethren of Christ, Whose heart was so pained for us all when He died on the holy Cross.
Even so we see a pious judge passing sentence upon the criminal with sorrow, and regretting the death which the law imposes. Here the act seems to be one of anger and harshness. So thoroughly good is meekness that even in such works of anger it remains, nay, it torments the heart most sorely when it must be angry and severe.
But here we must watch, that we be not meek contrary to God's honor and Commandment. For it is written of Moses that he was the very meekest man on earth, and yet, when the Jews had worshiped the golden calf and provoked God to anger, he put many of them to death, and thereby made atonement before God. Likewise it is not fitting that the magistrates should be idle and allow sin to have sway, and that we say nothing. My own possessions, my honor, my injury, I must not regard, nor grow angry because of them; but God's honor and Commandment we must protect, and injury or injustice to our neighbor we must prevent, the magistrates with the sword, the rest of us with reproof and rebuke, yet always with pity for those who have merited the punishment.
This high, noble, sweet work can easily be learned, if we perform it in faith, and as an exercise of faith. For if faith does not doubt the favor of God nor question that God is gracious, it will become quite easy for a man to be gracious and favorable to his neighbor, however much he may have sinned; for we have sinned much more against God. Behold, a short Commandment this, but it presents a long, mighty exercise of good works and of faith.
Thou shalt not commit adultery.
In this Commandment too a good work is commanded, which includes much and drives away much vice; it is called purity, or chastity, of which much is written and preached, and it is well known to every one, only that it is not as carefully observed and practised as other works which are not commanded. So ready are we to do what is not commanded and to leave undone what is commanded. We see that the world is full of shameful works of unchastity, indecent words, tales and ditties, temptation to which is daily increased through gluttony and drunkenness, idleness and frippery. Yet we go our way as if we were Christians; when we have been to church, have said our little prayer, have observed the fasts and feasts, then we think our whole duty is done.
Now, if no other work were commanded but chastity alone, we would all have enough to do with this one; so perilous and raging a vice is unchastity. It rages in all our members: in the thoughts of our hearts, in the seeing of our eyes, in the hearing of our ears, in the words of our mouth, in the works of our hands and feet and all our body. To control all these requires labor and effort; and thus the Commandments of God teach us how great truly good works are, nay, that it is impossible for us of our own strength to conceive a good work, to say nothing of attempting or doing it. St. Augustine says, that among all the conflicts of the Christian the conflict of chastity is the hardest, for the one reason alone, that it continues daily without ceasing, and chastity seldom prevails. This all the saints have wept over and lamented, as St. Paul does, Romans vii: "I find in me, that is in my flesh, no good thing."II. If this work of chastity is to be permanent, it will drive to many other good works, to fasting and temperance over against gluttony and drunkenness, to watching and early rising over against laziness and excessive sleep, to work and labor over against idleness. For gluttony, drunkenness, lying late abed, loafing and being without work are weapons of unchastity, with which chastity is quickly overcome. On the other hand, the holy Apostle Paul calls fasting, watching and labor godly weapons, with which unchastity is mastered; but, as has been said above, these exercises must do no more than overcome unchastity, and not pervert nature.
Above all this, the strongest defence is prayer and the Word of God; namely, that when evil lust stirs, a man flee to prayer, call upon God's mercy and help, read and meditate on the Gospel, and in it consider Christ's sufferings. Thus says Psalm cxxxvii:
