How can Christians resist Satan's influence?
What precautions can Christians take to guard against Satan's influence, as seen in Luke 22:3?

Seeing the Danger in Luke 22:3

“Then Satan entered Judas Iscariot, who was one of the Twelve.” (Luke 22:3)

Judas saw every miracle, heard every sermon, and still became a doorway for the enemy. His story warns that proximity to spiritual activity is no substitute for a guarded, surrendered heart.


A Heart Left Open: Why Judas Became Vulnerable

• Persistent, unconfessed sin (John 12:4-6)

• Love of money crowding out love for Christ (1 Timothy 6:10)

• Secret isolation while remaining outwardly involved (Psalm 66:18)


Practical Safeguards Against Satan’s Schemes

• Guard the heart daily

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

• Refuse footholds

– “Do not give the devil a foothold.” (Ephesians 4:27)

• Stay alert and sober-minded

– “Your adversary the devil prowls around like a roaring lion.” (1 Peter 5:8)


Walking in Daily Readiness

1. Put on the full armor of God (Ephesians 6:10-18)

2. Pray, “Lead us not into temptation, but deliver us from the evil one.” (Matthew 6:13)

3. Fill the mind with Scripture; speak it aloud when tempted (Psalm 119:11; Matthew 4:1-11)

4. Confess sin immediately—keep no secret places (1 John 1:9)


Courage to Stand in Community

• Invite accountability (Hebrews 3:13)

• Worship and fellowship regularly (Acts 2:42-47)

• Encourage one another to persevere in faith (Hebrews 10:24-25)


Strengthening Faith Through Obedience

• Practice generosity to break greed’s chain (2 Corinthians 9:6-8)

• Serve others instead of self (Mark 10:45)

• Walk by the Spirit, not the flesh (Galatians 5:16)

By guarding the heart, living transparently, and standing fully equipped in Christ, believers can close every door Judas left ajar and walk in confident freedom from Satan’s influence.
