What does "cast away" teach on purity?
What does "cast away the detestable things" teach about personal holiness and purity?

Setting the scene

Ezekiel 20:7: “And I said to them, ‘Cast away every one of you the detestable things of his eyes, and do not defile yourselves with the idols of Egypt; I am the LORD your God.’”

The verse records God’s charge to Israel as He reminded them of His deliverance from Egypt. Even before they left bondage, He demanded they abandon everything that offended His holiness. That same call echoes to believers today.


Unpacking “detestable things”

• Detestable (Hebrew: šequṣîm) refers to what God declares abhorrent—idols, immoral practices, anything unclean or corrupt.

• The phrase “of his eyes” highlights personal choice: whatever each person allowed to capture their gaze.

• “Idols of Egypt” represents both literal false gods and the broader world-system opposed to God (cf. 1 John 2:15-17).


The call to radical separation

• God did not ask Israel to ease idols out gradually; He demanded immediate removal—“cast away.”

• Holiness is impossible while clinging to what God hates (2 Corinthians 6:17-18).

• Purity requires decisive, sometimes painful, action (Matthew 5:29-30).


Holiness begins with the eyes and heart

• What we look at shapes what we love (Psalm 101:3).

• Jesus traces adultery to lustful looks (Matthew 5:28).

• Guarding the eye-gate helps guard the soul (Proverbs 4:23; Job 31:1).


Practical steps for casting away modern detestable things

• Identify—Take inventory of entertainment, relationships, online habits, possessions. Anything that dulls love for Christ is a candidate for disposal.

• Remove—Delete, unsubscribe, unfollow, discard. If it promotes impurity, eliminate it (Colossians 3:5).

• Replace—Fill the vacuum with Scripture, worship, service, Christ-centered friendships (Philippians 4:8).

• Remain—Daily keep short accounts with God; confess immediately when sin intrudes (1 John 1:9).

• Rely—Lean on the Spirit’s power; holiness is impossible in the flesh (Galatians 5:16).


Motivations for purity

• God’s character: “I am the LORD your God.” His nature defines holiness; His people must reflect Him (1 Peter 1:15-16).

• Grateful obedience: Deliverance from spiritual Egypt—sin and death—demands a holy response (Romans 12:1).

• Future fellowship: Purity preserves intimacy with God now and prepares us for eternity with Him (Hebrews 12:14).


The promise of transformation

Ezekiel later records God’s pledge: “I will sprinkle clean water on you, and you will be clean… I will give you a new heart and put a new spirit within you” (Ezekiel 36:25-26). God never commands without also providing the grace to obey.


Scripture echoes

Isaiah 1:16 – “Wash yourselves and be clean. Remove your evil deeds from My sight.”

2 Corinthians 7:1 – “Let us purify ourselves from everything that contaminates body and spirit.”

James 1:27 – “Keep oneself unstained by the world.”

1 John 3:3 – “Everyone who has this hope in Him purifies himself, just as He is pure.”

“Cast away the detestable things” calls every believer to ruthless, continual house-cleaning of the heart so that a holy God can dwell in ungrieved fellowship with His redeemed people.
