SECTION 1: DEFINING THE TERMS

First, let’s clarify what we mean.

• Possession is full control of a person by a demon.
  This is not possible for a Spirit-filled believer. The Holy Spirit and a demon cannot occupy the same dwelling.
• But Christians can be oppressed or influenced—that means external attacks, internal struggles, or repeated spiritual pressure.

Ephesians 4:27 warns:
“Do not give the devil a foothold.”

A foothold is access. If we allow it—through sin, wounds, or ignorance—the enemy can influence how we think, feel, or act.

SECTION 2: WHAT THE BIBLE SAYS

Let’s go to the Word.

• 2 Corinthians 10:4–5 tells us we’re in a spiritual war.

“We take every thought captive to obey Christ.”
This means demonic influence can affect our thinking, even as believers.

• 1 Peter 5:8–9 says:

“Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion…”

Why warn believers if they couldn’t be affected?
Because we can be influenced—but we don’t have to be controlled.

SECTION 3: BIBLICAL EXAMPLES OF BELIEVER INFLUENCE

1. Peter – Matthew 16:22–23
   Jesus says to Peter, “Get behind me, Satan!”
   Peter was a follower of Christ—but his thoughts were influenced by the enemy.
2. Ananias & Sapphira – Acts 5:1–3
   Peter says, “Why has Satan filled your heart to lie to the Holy Spirit?”
   They were part of the early church—but opened a door to deception.
3. Paul – 2 Corinthians 12:7
   He refers to a “messenger of Satan sent to torment me.”
   Even Paul wasn’t immune to attack—but he found grace to endure.

SECTION 4: HOW BELIEVERS OPEN DOORS

The enemy needs permission. Here are common access points:

• Unforgiveness
• Fear and anxiety
• Sexual sin
• Pride or rebellion
• Occult practices (even “harmless” ones)
• Generational sin
• Trauma or soul wounds

The good news is—we can shut the doors through repentance and deliverance.

SECTION 5: HOW TO RESIST DEMONIC INFLUENCE

James 4:7 gives us the key: “Submit to God. Resist the devil and he will flee.”

Daily tools for believers:

• The Word of God – renew your mind (Romans 12:2)
• Prayer and worship – draw close to God
• Confession and repentance – shut every open door
• Community and accountability – walk in the light
