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).
