Mark that the feast has not begun, though the guests are seated. The judgment stands at the threshold of the heavenly kingdom. The king speaks with a certain coldness, very unlike the welcome fit for a guest; and his question is one of astonishment at the rude boldness of the man who came there, knowing that he had not the proper dress. (That knowledge is implied in the form of the sentence in the Greek.) What, then, is the wedding garment? It can be nothing else than righteousness, moral purity, which fits for sitting at His table in His kingdom. And the man who has it not, is the nominal Christian, who says that he has accepted God's invitation, and lives in sin, not putting off 'the old man with his deeds,' nor putting on 'the new man, which is created in righteousness.' How that garment was to be obtained is no part of this parable. We know that it is only to be received by faith in Jesus Christ, and that if we are to pass the scrutiny of the king, it must be as 'not having our own righteousness,' but His made ours by faith which makes us righteous, and then by all holy effort, and toil in His strength, we must clothe our souls in the dress which befits the banqueting hall; for only they who are washed and clothed in fine linen, clean and white, shall sit there. But Christ's purpose here was not to explain how the robe was to be procured, but to insist that it must be worn.
'He was speechless,'--or, as the word means, 'muzzled.' The man is self-condemned, and, having nothing to say in extenuation, the solemn promise is pronounced of ejection from the lighted hall, with limbs bound so that he cannot struggle, and consignment to the blackness outside, of which our Lord adds, in words not put into the king's mouth, but which we have heard from Him before, 'There shall be the [well-known and terrible] weeping and gnashing of teeth--awful though figurative expressions for despair and passion.
Both parts of the parable come under one law, and exemplify one principle of the kingdom, that its invitations extend more widely than the real possession of its gifts. The unbelieving Jew, in one direction, and the unrighteous Christian in another, are instances of this.
This is not the place to discuss that wide and well-worn question of the ground of God's choice. That does not enter into the scope of the parable. For it, the choice is proved by the actual participation in the feast. They who do not choose to receive the invitation, or to put on the wedding garment, do, in different ways, show that they are not 'chosen' though 'called.' The lesson is, not of interminable and insoluble questionings about God's secrets, but of earnest heed to His gracious call, and earnest, believing effort to make the fair garment our very own, 'if so be that being clothed we shall not be found naked.'
