Revelation 3:5

He that overcometh. See on ch. 2:7.

Clothed. That is, with immortality in the life to come.

White raiment. See on v. 4.

Blot out. See on Acts 3:19. The figurative phrase “not blot out” assures the repentant sinner that his sins have been forgiven, and warns the unrepentant that his name will be removed from the book of life. His very identity as a person will cease to exist; he will no longer have a place among created beings.

Book of life. See on Phil. 4:3; cf. Rev. 13:8; 20:15.

Confess his name. That is, acknowledge him as a loyal, devoted follower. Christ is the advocate and intercessor, the great high priest of all who claim His righteousness (see 1 John 2:1, 2; cf. Matt. 10:32, 33; Heb. 8:1–6).

Before his angels. The “broader and deeper purpose” of the plan of redemption is “to vindicate the character of God before the universe”. When Christ in His role as intercessor and high priest presents His ransomed people before the throne of God, He thereby provides the angelic hosts with a convincing testimony that the ways of God are just and true. They see the righteousness of God vindicated, alike in His “strange act” (Isa. 28:21) of committing the unrepentant to destruction and in His pardon of sinners who accept His saving grace by faith. Without the high priestly intercession of Christ, such otherwise mysterious acts of God might appear to the intelligences of the universe as arbitrary and unjustified.
