The grim sentence that Christ pronounces here ought to make us tremble at this vice. As I have said, the one who judges always has a log in his eye as far as God is concerned, while the one who is being judged has only a speck. Now, the log is an infinitely graver sin than the speck, that is, the kind of sin that damns altogether and leaves us no grace. However great our sins and transgressions may be otherwise, He can forgive all of these, as He shows by calling the neighbor’s sin a “speck.” But you spoil everything when to these sins you add the abomination and the filth of judging and condemning someone else on account of his faults and when you refuse to forgive the way you want God to forgive you. You go ahead refusing to see the log, and you imagine that you are without sin. But if you recognized yourself, as has been said, you would also refrain from judging your neighbor. Thus your log would be called a little speck, and it would obtain the forgiveness of sins. You would also be willing to forgive and tolerate and excuse someone else’s speck, in view of the fact that God forgives and pardons your log.” (Luther’s Works, v. 21, pages 222).

“There shall be no such perversion in My kingdom,” Christ says, “but first you must make the big villain pious, the one you find in your own skin when you examine yourself carefully. Once you have accomplished this much, there will be time enough to make a little villain pious. But it will amaze you how much trouble the big villain will cause you every day. Therefore I am willing to guarantee and to stake My life on it that you will never get around to removing the speck from someone else’s eye, and will have to say: ‘How can I deal with other people and make them pious first? I cannot even make myself pious or get rid of my log.’ Thus you will probably leave your brother’s speck unharmed.” You see, what Christ means to say as a summary of this teaching is that we should willingly practice forgiveness, patient forbearance, and humility in our relations with one another; that is what the situation would have to be like if we followed this teaching. Then everything in Christendom would move along correctly and harmoniously, as it should, and God would be with us. But through his members and through Sectarianism the devil keeps this from happening. (Luther’s Works, v. 21, pages 221-222).
