What personal actions can prevent spiritual "spreading" of sin in our lives?

Recognize Sin’s Contagious Nature

“Do you not know that a little leaven leavens the whole lump?” (1 Corinthians 5:6)

Paul’s picture of leaven tells us that sin left unchecked never stays small; it spreads through thoughts, habits, relationships, and the church itself. Knowing its contagious nature motivates decisive, personal action.

Practical Steps for Each Day

1. Start with Scripture and prayer before other voices enter.

2. Ask the Spirit to spotlight any “leaven” trying to work into attitudes or actions.

3. Name and confess sin the moment conviction comes; don’t wait for it to grow roots.

4. Replace the lie behind the sin with a specific promised truth from God’s Word.

5. Choose one tangible act of obedience—an encouraging word, a generous gift, a surrendered moment—to reinforce new patterns.

6. Review the day at night; thank God for victories and confess failures.

Encouragement from Other Passages

• 2 Timothy 2:22—“Flee from youthful passions and pursue righteousness…”

• Ephesians 6:11—“Put on the full armor of God, so that you can stand against the schemes of the devil.”

• James 4:7—“Submit yourselves, then, to God. Resist the devil, and he will flee from you.”

Purposeful vigilance, swift repentance, and Spirit-empowered obedience keep the “leaven” from spreading and allow the whole “lump” of our lives to honor the Lord.
