Revelation 22:15

The opposite of the blessings described in Revelation 22:14 is exclusion from the New Jerusalem, namely, eternity in the lake of fire (Revelation 20:15; Revelation 21:8). Jesus described the people who will not enter the city by the works that mark their lives of unbelief. "Dogs" is a metaphor for the morally impure (cf. Deuteronomy 23:18; 2 Kings 8:13; Psalms 22:16; Psalms 22:20; Isaiah 56:10; Matthew 7:6; Matthew 15:26; Mark 7:27; Philippians 3:2-3). In John’s day many dogs were wild, aggressive scavengers. [Note: Robertson, 6:485; Johnson, p. 602.] Their fate should warn believers not to fall into apostasy and its associated vices. [Note: Wall, p. 266.] The other types of individuals named here appear in other lists of wicked unbelievers (cf. Revelation 21:8).
