Detecting spiritual impurity in life?
How can we discern spiritual "contamination" in our lives, as in Leviticus 13:49?

The Picture in Leviticus 13:49

“and if the spot in the fabric or leather, or in the warp or weft, or in any leather article is greenish or reddish, it is a diseased spot and must be shown to the priest.” (Leviticus 13:49)

Leviticus treats mildew as more than an eyesore; it is an uncleanness that spreads unless exposed and dealt with. The text supplies a living illustration of how sin—spiritual contamination—can settle into ordinary places of life and quietly corrupt.


Why the Stain Matters

• Sin defiles what should be devoted to God (Isaiah 59:2).

• Contamination spreads: “A little leaven leavens the whole batch.” (1 Corinthians 5:6)

• Unchecked impurity robs us of fellowship and testimony (Isaiah 1:18; 1 Peter 1:15-16).


Where Spiritual Contamination Hides Today

• Thought life: lingering bitterness, lust, unbelief (Matthew 5:27-28).

• Speech: gossip, coarse joking, half-truths (Ephesians 4:29).

• Relationships: unforgiveness, manipulation, envy (James 3:14-16).

• Habits and media: entertainment that normalizes sin (Psalm 101:3).

• Stewardship: greed, waste, dishonest gain (1 Timothy 6:9-10).


Tests for Detection

Like Israel brought garments to a priest, we bring our hearts to the Lord.

• Scripture test – hold attitudes and actions against the mirror of the Word (Hebrews 4:12).

• Spirit’s conviction – heed the gentle “spotlight” of the Holy Spirit (John 16:8).

• Fruit test – examine outcomes: are love, joy, peace increasing or is decay setting in? (Galatians 5:22-23).

• Community test – accept loving correction from mature believers (Proverbs 27:6).


Responding Once the Stain Is Found

1. Acknowledge: “Search me, O God… see if there is any offensive way in me.” (Psalm 139:23-24).

2. Confess specifically: “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” (1 John 1:9).

3. Remove the source: cut off whatever feeds the impurity (Matthew 5:29-30).

4. Apply the cross: trust the finished work of Christ for cleansing (Hebrews 9:14).

5. Restore fellowship: replace the old pattern with obedience (Ephesians 4:22-24).


Guarding Against Future Contamination

• Daily washing in the Word (Ephesians 5:26).

• Ongoing dependence on the Spirit (Galatians 5:16).

• Transparent fellowship with believers (Hebrews 10:24-25).

• Quick repentance when new spots appear (2 Corinthians 7:1).

• Vigilant boundary-setting: “Have no fellowship with the fruitless deeds of darkness, but rather expose them.” (Ephesians 5:11).

The same God who called for mildew-stained garments to be examined and cleansed now calls us to live unstained by the world (James 1:27). He provides everything needed—His Word, His Spirit, and the blood of His Son—to discern and remove every trace of spiritual contamination.
