Matthew 22:12

And he saith unto him, Friend, how camest thou in hither not having a wedding garment? And he was speechless.

That man's apparel was an insult to the occasion, indicating that immoral and shameful conduct on the part of Christians is an insult to God that will at last be punished. We may not excuse him on grounds that he was poor, unable to obtain a wedding garment, or that he had no chance to supply one. Note that the man himself was speechless. It was totally his fault, and he could not think of any word to utter in defense of what he had done. We do not appeal to traditions handed down, nor to customs of monarch's who always provided royal garments for their guests, nor to anything else except the speechlessness of that intruder who thus marred the happy festivities by entering without a wedding garment. He could not defend himself or offer any excuse; rash is the person who will trump up one for him. What kind of person could fabricate a defense for that rude person's insult of the king? In cases where men have sought to defend him, it appears that their cavil should be avoided and stored up for the time when those persons who make it will need it in their own defense; and yet it is certain that such persons will be as speechless as was he. This simply means that, at last, every condemned sinner will have to agree in his very heart that he deserves condemnation, and that it is no one's fault but his own!
