Question (from Contact Us)

[Lamb]

We had someone ask a question through Contact Us and since we can't communicate through Contact Us, I thought I'd copy and paste for members to respond:

My friend converted to become a Muslim can he come back to Christianity if he repents?

 

[Frankj]

Jesus addressed this type of condition directly in the story of the prodigal son.

He will have no problem with God welcoming him back but on a practical side he may have a huge problem with other Muslims when he tries to leave Islam.

This is something I've been discussing with one of our elders. At my church the prevailing view is that we have eternal security and that this person was always a Christian if they truly converted to Jesus at any point in their life.

My view is the opposite, that we can walk away and do our own thing. I share Frank's sentiments about the prodigal son and the notion that God will always take us back.

We could discuss the fate of the prodigal son had he died before coming back, although I'm not sure it's relevant to the person asking the question given they are apparently wanting to return.

Call upon the Name of the Lord and you will be saved!


I believe in my heart that Jesus Christ is the Son of God, that He died on the cross for my sins, and that You raised Him from the dead. I receive Jesus Christ as my Lord and Savior.


If you confess with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved.”


Spiritual Dynamics of Calling on His Name
That’s the heart of the gospel, —straight from Romans 10:13:
1. Universal Invitation
• Everyone—no exclusions. Jew, Gentile, rich, poor, soldier, child.
• Salvation is open to all who call sincerely.
2. The Act of Calling
• Not silent belief alone, but a spoken cry of faith.
• It’s both prayer and declaration: aligning heart and mouth.
3. The Name of the Lord
• In Scripture, the Name represents His authority, character, and covenant.
• To call on His Name is to invoke His lordship and saving power.
4. Guaranteed Outcome
• “Will be saved”—not “might,” not “could.”
• God’s promise is absolute: calling activates salvation.

Battlefield Application
• In warfare, calling on His Name is the emergency protocol.
• Like a soldier’s radio call for reinforcements, it summons divine rescue.
• Psalm 91 echoes this: “He will call on Me, and I will answer him; I will be with him in trouble; I will deliver him and honor him.” (v.15)


Prayer of Salvation
Key Scriptural Anchors
• Romans 10:9–10 — Believe in your heart, confess with your mouth.
• John 1:12 — Receive Him, become children of God.
• Ephesians 2:8–9 — Salvation by grace through faith.
• Revelation 3:20 — Jesus stands at the door and knocks.
This prayer is not a formula but a faith declaration: believing in the heart and confessing with the mouth. It’s the covenant entry point into the Kingdom. You've taken the "oath", enlisting in the Army of God!


Spiritual Mechanics Behind the Phrase
Heart + Mouth = Activation
• Belief in the heart is the internal conviction—faith that aligns with truth.
• Confession with the mouth is the external release—spoken agreement that activates spiritual reality.
Together, they form a covenantal trigger: belief justifies, confession seals. Forever a child of God!

Warfare Application
In spiritual battle, this principle becomes a weaponized declaration:
• Heart belief anchors your identity in Christ.
• Mouth confession deploys authority against darkness.
Examples:
• “I am the righteousness of God in Christ.”
• “No weapon formed against me shall prosper.”
• “I overcome by the blood of the Lamb and the word of my testimony.”

This formula—heart belief + mouth confession—is foundational:
• It’s the entry point to salvation, the engine of spiritual warfare, and the seal of covenant victory.
• It aligns with Psalm 91’s rhythm: “I will say of the Lord…” He is my refuge and my fortress: my God;.” → followed by divine protection- "in Him will I trust".
