He that overcometh,.... The deadness, formality, and imperfection of this church state; gets over these things, and is among the few names in it:the same shall be clothed in white raiment; the Vulgate Latin, Syriac, Arabic, and Ethiopic versions, read, "thus shall he be clothed in white raiment"; he shall have abundance of spiritual peace and joy, great success and prosperity, both inward and outward, in himself, and in the church; and triumph over all his enemies, sin, Satan, the world, death, and every other enemy; and not only be clothed with change of raiment, the pure and spotless righteousness of Christ, but shall enjoy eternal glory and happiness!
the allusion seems to be to the custom of the Jewish sanhedrim in judging of priests fit for service ;"they examined the priests concerning their genealogies and blemishes; every priest in whom was found anything faulty in his genealogy, he was clothed in black and veiled in black, and went out of the court; but everyone that was found perfect and right, Mynbl vbwl, "he was clothed in white", and went in and ministered with his brethren the priests.'
'And I will not blot out his name out of the book of life; by which is meant the choice of persons to everlasting life and salvation; and this being signified by a book, and by writing names in it, shows the exact knowledge God has of his elect, the value he has for them, his remembrance of them, his love to them, and care for them; and that this election is of particular persons by name, and is sure and certain; for those whose names are written in it shall never be blotted out, they will always remain in the number of God's elect, and can never become reprobates, or shall ever perish; because of the unchangeableness of the nature and love of God, the firmness of his purposes, the omnipotence of his arm, the death and intercession of Christ for them, their union to him, and being in him, the impossibility of their seduction by false teachers, and the security of their persons, grace, and glory in Christ, and in whose keeping this book of life is; which respects not this temporal life, that belongs to the book of providence, but a spiritual and eternal life, from whence it has its name.
But I will confess his name before my Father and before his angels; which shows that Christ has an exact and perfect knowledge of all the chosen ones, he knows them by name; and that he has a strong and affectionate love for them, and is not ashamed of them, of their cause, of their persons, and of their relation to him; and that he does and will own, acknowledge, and approve of them, both here and hereafter: and the confession he will make of them will be in their praise; in praise of their persons and the comeliness of them, which he has put upon them; and of their graces, though they are his own; and of their good works as the fruits of grace: and this will be made before his Father, who chose these persons, and gave them to him to preserve and save; and before the angels, who rejoice at their salvation and happiness; and this will be at the last day;See Gill on "Mt 10:32".
