What sins does Revelation 22:15 warn of?
How does Revelation 22:15 warn against specific sinful behaviors?

Setting the Scene: The Last Word on Entrance and Exclusion

“Outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices falsehood.” (Revelation 22:15)

John has just pictured the New Jerusalem—a place of perfect light, healing, and face-to-face fellowship with God. Then, in a single sentence, he reminds us with sobering clarity that not everyone enters. The verse is an echo of Revelation 21:8 and underscores that final exclusion is literal, irreversible, and just.


Six Behaviors Named—And Why They Matter

• Dogs

• Scripture uses “dogs” for the shamelessly impure (Philippians 3:2) and, in Old Testament law, male cult prostitutes (Deuteronomy 23:17-18).

• The term captures those who refuse moral restraint and despise holiness.

• Sorcerers

• Greek pharmakoi points to the use of drugs, charms, or occult practices to manipulate spiritual power (Deuteronomy 18:10-12; Acts 19:18-19).

• God condemns every attempt to seek guidance or power apart from Him.

• Sexually Immoral

• Porneia covers all sexual activity outside the covenant of biblical marriage (1 Corinthians 6:18-20; Hebrews 13:4).

• Unrepentant sexual sin rejects God’s design for purity and illustrates rebellion against His authority.

• Murderers

• The sixth commandment (Exodus 20:13) is absolute; Jesus extends it to hatred in the heart (Matthew 5:21-22).

• Life is God’s gift; taking it unlawfully insults the Giver.

• Idolaters

• Anything placed above God—whether statue, career, or desire—becomes an idol (Exodus 20:3-5; Colossians 3:5).

• Idolatry always substitutes a created thing for the Creator, forfeiting fellowship with Him.

• Lovers and Practitioners of Falsehood

• Lying lips are “detestable” to the Lord (Proverbs 12:22); Satan is “the father of lies” (John 8:44).

• Persisting in deception aligns a person with darkness rather than the Truth who is Christ (John 14:6).


What “Outside” Really Means

Revelation 21:8 clarifies the destiny: “the lake that burns with fire and sulfur, which is the second death.” Being “outside” is not mere social distance but eternal separation from the presence, blessings, and light of God. Sin’s pleasure is momentary; its cost is forever.


The Open Invitation Inside the City

Only one verse earlier, John wrote, “Let the one who is thirsty come; and let the one who desires take the water of life freely.” (Revelation 22:17)

Salvation is still offered to all who repent and trust the Lamb (John 3:16; Acts 3:19). The warning of verse 15 highlights the urgency of responding to that gracious call.


Living the Difference Today

• Examine your life in light of these six categories; ask God to expose hidden sins (Psalm 139:23-24).

• Flee what Scripture condemns; do not negotiate with it (2 Timothy 2:22).

• Pursue holiness, empowered by the Spirit, because without it “no one will see the Lord” (Hebrews 12:14).

• Cling to truth, refuse deceit, and let your “Yes” be yes (Ephesians 4:25).

• Keep your eyes on the city to come, where “nothing unclean will ever enter” (Revelation 21:27).
