Topical Lexicon
Core Idea

Strong’s Greek 4510 depicts the state or act of moral and spiritual filthiness—an inner pollution that stands in stark contrast to the purity God requires. Its solitary New Testament appearance (Revelation 22:11) imbues the term with an eschatological weight: when final judgment arrives, a person’s chosen moral condition will be irrevocably fixed.

Singular Occurrence and Immediate Context

Revelation 22:11: “Let the evildoer continue to do evil, and the filthy continue to be filthy; let the righteous continue to practice righteousness, and the holy continue to be holy.”

Placed just before the promise of Christ’s imminent return (Revelation 22:12–13), the word sharpens the contrast between two unalterable destinies. The angel’s declaration is not a divine endorsement of sin but a sober warning that persistent refusal to repent will culminate in permanent separation from God (Revelation 22:14–15).

Old Testament Background

1. Ritual uncleanness—Leviticus 13–15 and Numbers 19—illustrates how impurity barred access to corporate worship.
2. Prophetic imagery—Isaiah 64:6 describes righteousness as “filthy rags,” and Zechariah 3:3–5 depicts Joshua clothed in “filthy garments” until God provides clean vestments.
3. These passages lay the foundation for understanding inward corruption as something only divine intervention can remove (Psalm 51:2).

Filthiness versus Holiness

• Filthiness embodies willful rebellion (Proverbs 30:12).
• Holiness signifies separation unto God, driven by grace (1 Peter 1:15–16).

Revelation 22:11 therefore intensifies the familiar biblical dichotomy: uncleanness excludes (Ephesians 5:5), while holiness inherits (Hebrews 12:14).

Pastoral and Ministerial Applications

1. Call to Repentance: The verse presses evangelistic urgency; while forgiveness is available now (1 John 1:9), a time is coming when moral trajectories become unchangeable.
2. Assurance for the Faithful: Believers are encouraged to persevere, knowing that continuing in holiness will be acknowledged eternally (Revelation 22:12).
3. Warning against Complacency: Churches must not presume upon God’s patience (2 Peter 3:9–14). Ongoing sanctification—“washing of water by the word” (Ephesians 5:26)—remains essential.

Witness of Early Christianity

Clement of Rome called the church to “cast away every wicked and filthy desire” (First Epistle, 30). Irenaeus, contrasting darkness and light, viewed persistent impurity as self-imposed exile from God’s kingdom (Against Heresies, 4.39.4). Such writings echo the finality of Revelation 22:11 and reinforce the necessity of present obedience.

Eschatological Implications

• Fixed Character: At Christ’s return, moral character crystallizes; there is no post-mortem purification.
• Just Retribution: The filthy inherit the “lake that burns with fire and sulfur” (Revelation 21:8), whereas the holy enjoy “the right to the tree of life” (Revelation 22:14).
• Cosmic Cleansing: New creation excludes every defilement (Revelation 21:27), fulfilling prophetic visions of total purification (Isaiah 35:8).

Practical Counsel for Believers

1. Receive Christ’s cleansing: “To Him who loves us and has released us from our sins by His blood” (Revelation 1:5).
2. Walk in continual confession and renewal (James 1:21).
3. Maintain expectancy: “Everyone who has this hope in Him purifies himself, just as He is pure” (1 John 3:3).
4. Proclaim the gospel: Warn the impenitent that the opportunity for cleansing is time-bound (Hebrews 4:7).

Summary

Strong’s Greek 4510 captures the grim reality of entrenched moral impurity and the irreversible consequences awaiting those who cling to it. Its lone biblical appearance, strategically situated at the close of Scripture, serves as a solemn invitation: abandon filthiness today and pursue the holiness without which no one will see the Lord.
