Satan in Judas: Spiritual vulnerability?
How does Satan entering Judas in Luke 22:3 illustrate spiritual vulnerability to evil?

The Passage

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


Seeing the Scene

• Jesus has just predicted His betrayal (Luke 22:1-2).

• Religious leaders are plotting, but Satan moves straight for a willing heart.

• Judas, though among the Twelve, carries hidden sin (John 12:4-6).


Layers of Spiritual Vulnerability in Judas

• Unrepentant Sin

– Greed had long ruled him (John 12:6).

– Unchecked desire opened a door: “do not give the devil a foothold” (Ephesians 4:27).

• Hardening to Truth

– Repeated exposure to Jesus’ teaching without surrender produced callousness (Hebrews 3:12-13).

• Isolation Despite Proximity

– Outwardly close to believers, inwardly detached (1 John 2:19).

• Willful Agreement

– He “sought an opportunity” (Luke 22:6); Satan could now “enter” (John 13:27).


What “Satan Entered” Means

• More than temptation—direct, personal control.

• Not symbolic; Scripture states it literally.

• Demonstrates the devil’s desire to exploit open spiritual doors (1 Peter 5:8).


The Enemy’s Strategy Exposed

1. Probe for an unguarded area (greed, bitterness, lust).

2. Whisper plausible lies (“Thirty pieces of silver are worth it”).

3. Secure the heart’s consent—then dominate.


Safeguards for Believers Today

• Daily confession and repentance (1 John 1:9).

• Wholehearted love for Christ rather than divided loyalties (Matthew 6:24).

• Accountable fellowship that confronts hidden sin (Hebrews 10:24-25).

• Active resistance: “Submit yourselves therefore to God. Resist the devil, and he will flee from you.” (James 4:7).

• Full spiritual armor (Ephesians 6:10-18).


Key Takeaways

• Position alone (even among the Twelve) does not guarantee protection.

• Small, tolerated sins can become entry points for great evil.

• Satan needs cooperation; surrender to Christ shuts the door.
