Revelation 3:4

Thou hast a few names even in Sardis - A few persons, names being put for those who bore them. And as the members of the Church were all enrolled, or their names entered in a book, when admitted into the Church or when baptized, names are here put for the people themselves. See Revelation 3:5.

Have not defiled their garments - Their souls. The Hebrews considered holiness as the garb of the soul, and evil actions as stains or spots on this garb. So in Shabbath, fol. 152, 2: "A certain king gave royal garments to his servants: those who were prudent folded them up, and laid them by in a chest; those who were foolish put them on, and performed their daily labor in them. After some time the king asked for those royal robes; the wise brought theirs white and clean, the foolish brought theirs spotted with dirt. With the former the king was well pleased; with the latter he was angry. Concerning the former he said: Let those garments be laid up in my wardrobe, and let the persons go home in peace. Of the latter he said: Let the garments be put into the hands of the fuller, and cast those who wore them into prison." This parable is spoken on these words of Ecclesiastes, Ecclesiastes 12:7 : The spirit shall return to God who gave it.

They shall walk with me in white - They shall be raised to a state of eternal glory, and shall be for ever with their Lord.

Thou hast a few names even in Sardis - See the analysis of the chapter. The word "names" here is equivalent to "persons"; and the idea is, that even in a place so depraved, and where religion had so much declined, there were a few persons who had kept themselves free from the general contamination. In most cases, when error and sin prevail, there may be found a few who are worthy of the divine commendation; a few who show that true religion may exist even when the mass are evil. Compare the notes on Romans 11:4.

Which have not defiled their garments - Compare the notes on Jde 1:23. The meaning is, that they had not defiled themselves by coming in contact with the profane and the polluted; or, in other words, they had kept themselves free from the prevailing corruption. They were like persons clothed in white walking in the midst of the defiled, yet keeping their raiment from being soiled.

And they shall walk with me in white - White is the emblem of innocence, and is hence appropriately represented as the color of the raiment of the heavenly inhabitants. The persons here referred to had kept their garments uncontaminated on the earth, and as an appropriate reward it is said that they would appear in white raiment in heaven. Compare Revelation 7:9; Revelation 19:8.

For they are worthy - They have shown themselves worthy to be regarded as followers of the Lamb; or, they have a character that is suited for heaven. The declaration is not that they have any claim to heaven on the ground of their own merit, or that it will be in virtue of their own works that they will be received there; but that there is a fitness or propriety that they should thus appear in heaven. We are all personally unworthy to be admitted to heaven, but we may evince such a character as to show that, according to the arrangements of grace, it is fit and proper that we should be received there. We have the character to which God has promised eternal life.

3:4 Yet thou hast a few names - That is, persons. But though few, they had not separated themselves from the rest; otherwise, the angel of Sardis would not have had them. Yet it was no virtue of his, that they were unspotted; whereas it was his fault that they were but few. Who have not defiled their garments - Either by spotting themselves, or by partaking of other men's sins. They shall walk with me in white - in joy; in perfect holiness; in glory. They are worthy - A few good among many bad are doubly acceptable to God. O how much happier is this worthiness than that mentioned, Revelation 16:6 .
