9. Thus you see that this text does not at all permit us to conclude from it that forgiveness of sins is obtained by works; for Christ here speaks to those who are already children of grace, and does not instruct them how to obtain by works, as the Papists dream, the forgiveness of sins, which they already had by grace; however, he here teaches them how they are to conduct themselves, when they go forth and preach, toward the people who persecute, judge, condemn them, and afflict them with all kinds of torment and misfortune; that they immediately do the contrary, not judge, nor condemn, but forgive and give; and then they shall also be neither judged nor condemned before God or the world. And even though the world judge them, still God will not condemn them, as it is said in Psalm 37:13-40. So it shall also be forgiven and given them again.
10. Thus Christ admonishes his disciples with these words, that they diligently perform the duties of their office and preach with courage, let it offend whom it may, and that nothing whatever may lead them astray, even though all the world revile and curse; let them only freely continue and they shall be richly rewarded; for it is already determined in heaven that there shall be given unto them full measure, pressed down, shaken together and running over.
11. From all this it is certainly clear, that Christ does not here speak of that righteousness, of how a man becomes just before God, which takes place alone through faith in Jesus Christ, but teaches his disciples how to lead a good life here on earth among unbelievers, by which they may be of great benefit to those who judge and condemn them. When they do such things, it shall be rewarded unto them again both here and hereafter; not that they thereby merit the forgiveness of sins; for no work, be it ever so good, is able to accomplish this; but when they on this account suffer or lose anything, it shall be returned to them even here in this life an hundred fold, as is written in Mark 10:30, and in the life to come they will be more gloriously arrayed and adorned than other saints. Why? Because they have suffered and done more for Christ’s sake than others. For Daniel the prophet says, Daniel 12:3, that the teachers shall shine as the brightness of the firmament after the resurrection of the dead, and they that turn many to righteousness as the stars forever and ever. And St. Paul in Corinthians 15:41 says: “For one star differeth from another star in glory. So also is the resurrection of the dead.”
12. The Lord further says: When you fail to do thus, but return evil for evil, it shall be measured to you again, “for with what measure you mete, it shall be measured to you again.” For by thus judging and condemning those who judge and condemn you, you sufficiently show that you are not my true disciples, and have not yet the forgiveness of sins, or else you would do what I have commanded you. From which it follows further that your faith is not right. So with you it will be changed, and you will hear from me that you have no faith and are false Christians.
