Revelation 3:5

Raiment - Clothing; apparel; covering.

I will not blot out his name - This may be an allusion to the custom of registering the names of those who were admitted into the Church in a book kept for that purpose, from which custom our baptismal registers in Churches are derived. These are properly books of life, as there those who were born unto God were registered; as in the latter those who were born in that parish were enrolled. Or there may be allusions to the white raiment worn by the priests, and the erasing of the name of any priest out of the sacerdotal list who had either sinned, or was found not to be of the seed of Aaron. In Middoth, fol. 37, 2: "The great council of Israel sat and judged the priests. If in a priest any vice was found they stripped of his white garments and clothed him in black, in which he wrapped himself, went out, and departed. Him in whom no vice was found they clothed in white, and he went and took his part in the ministry among his brother priests."

I will confess his name - I will acknowledge that this person is my true disciple, and a member of my mystical body. In all this there may also be an allusion to the custom of registering citizens. Their names were entered into books, according to their condition, tribes, family, etc.; and when they were dead, or had by unconstitutional acts forfeited their right of citizenship, the name was blotted out, or erased from the registers. See the note on Exodus 32:32.

He that overcometh - See the notes on Revelation 2:7.

The same shall be clothed in white raiment - Whosoever he may be that shall overcome sin and the temptations of this world, shall be admitted to this glorious reward. The promise is made not only to those in Sardis who should be victorious, but to all in every age and every land. The hope that is thus held out before us, is that of appearing with the Redeemer in his kingdom, clad in robes expressive of holiness and joy.

And I will not blot out his name out of the book of life - The book which contains the names of those who are to live with him forever. The names of his people are thus represented as enrolled in a book which he keeps - a register of those who are to live forever. The phrase "book of life" frequently occurs in the Bible, representing this idea. See the notes on Philippians 4:3. Compare Revelation 15:3; Revelation 20:12, Revelation 20:15; Revelation 21:27; Revelation 22:19. The expression "I will not blot out" means, that the names would be found there on the great day of final account, and would be found there forever. It may be remarked, that as no one can have access to that book but he who keeps it, there is the most positive assurance that it will never be done, and the salvation of the redeemed will be, therefore, secure. And let it be remembered that the period is coming when it will be felt to be a higher honor to have the name enrolled in that book than in the books of heraldry - in the most splendid catalogue of princes, poets, warriors, nobles, or statesmen that the world has produced.

But I will confess his name, ... - I will acknowledge him to be my follower. See the notes on Matthew 10:32.

3:5 He shall be clothed in white raiment - The colour of victory, joy, and triumph. And I will not blot his name out of the book of life - Like that of the angel of the church at Sardis: but he shall live for ever. I will confess his name - As one of my faithful servants and soldiers.
