How to prevent spiritual decay in faith?
How can believers guard against the spiritual decay described in Job 18:13?

Setting the Scene: Decay in Job 18:13

“ ‘It devours the parts of his skin; the firstborn of death devours his limbs.’ ” (Job 18:13)

• Bildad pictures sin and judgment as an aggressive disease, eating a person alive.

• Spiritual decay, like physical rot, starts small, spreads silently, and eventually consumes everything.


Recognizing Today’s Threats

• Hidden sin (Psalm 66:18)

• Habitual compromise with the world’s values (James 4:4)

• Neglect of Scripture and prayer (Matthew 4:4)

• Isolation from godly fellowship (Hebrews 10:24-25)

• Pride that resists correction (Proverbs 16:18)


Guarding the Heart: Practical Steps

1. Daily self-examination

‑ “Search me, O God, and know my heart…” (Psalm 139:23-24)

‑ Ask the Spirit to spotlight even “small” sins before they spread.

2. Immediate confession and cleansing

‑ “If we confess our sins, He is faithful and just to forgive…” (1 John 1:9).

‑ Keep a short account with God; let nothing linger.

3. Saturate the mind with Scripture

‑ “I have hidden Your word in my heart that I might not sin against You.” (Psalm 119:11)

‑ Read, memorize, and meditate so truth crowds out decay.

4. Walk by the Spirit

‑ “Walk by the Spirit, and you will not gratify the desires of the flesh.” (Galatians 5:16)

‑ Depend on His power, not sheer willpower.

5. Cultivate accountable relationships

‑ “Encourage one another daily… so that none of you may be hardened by sin’s deceitfulness.” (Hebrews 3:13)

‑ Invite trusted believers to ask hard questions.

6. Guard the inputs

‑ “Above all else, guard your heart, for everything you do flows from it.” (Proverbs 4:23)

‑ Filter media, conversations, and influences that erode holiness.

7. Practice regular spiritual disciplines

‑ Fasting, worship, service, generosity—each keeps the soul supple and responsive.

8. Remember the consequences

‑ Bildad’s grim picture warns that unchecked sin never stays small. Keep eternity in view (Romans 6:23).


Strengthening Shield: Scripture and Fellowship

• Armor of God—Ephesians 6:10-18 equips against decay’s assault.

• Wise companions—“Bad company corrupts good character.” (1 Corinthians 15:33) Choose allies who sharpen.

• Church ordinances—regular communion and baptismal remembrance anchor the heart in Christ’s finished work.


Living in Vigilance and Hope

• Spiritual decay is preventable when believers remain alert and dependent on the Lord.

• Christ has “come that [we] may have life, and have it in all its fullness” (John 10:10); His life conquers every rot.

• Stay watchful, stay nourished, stay connected—then the “firstborn of death” finds no foothold.
