1 Cor 15:2's role in salvation doubts?
How can 1 Corinthians 15:2 guide our response to doubts about salvation?

Scripture Foundation

“By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.” (1 Corinthians 15:2)


Context in 1 Corinthians 15

• Paul opens the chapter reminding the believers of the gospel he “received” and “passed on” (15:1, 3).

• The chapter locks our assurance to the historical, bodily resurrection of Jesus (15:3-8, 20).

• Salvation is presented as both a completed reality (“you are saved”) and an ongoing stance (“if you hold firmly”).


Key Truths for Our Assurance

• The gospel saves; our grip on that gospel shows its authenticity in us.

• Holding firmly is evidence, not a self-generated work—true faith clings because God preserves (cf. 1 Peter 1:5).

• Belief “in vain” refers to empty, surface assent detached from the risen Christ.


Holding Firmly: Practical Steps

1. Rehearse the gospel daily—Christ died for our sins, was buried, rose on the third day (15:3-4).

2. Anchor identity to Christ, not shifting feelings (Galatians 2:20).

3. Gather with believers who remind one another of this truth (Hebrews 10:24-25).

4. Refuse counterfeit gospels that add works or subtract the resurrection (Galatians 1:6-9).

5. Face doubts by returning to Scripture, not inward speculation (Psalm 119:105).


Companion Passages to Strengthen Faith

John 10:28-29—no one snatches His sheep from His hand.

Romans 8:38-39—nothing separates us from the love of God in Christ.

Colossians 1:22-23—reconciled “if indeed you continue in the faith, established and firm.”

2 Timothy 1:12—He is able to guard what is entrusted until that day.


When Doubts Arise: Remember the Gospel

• Doubt often surfaces when gazing at personal failures; the gospel redirects focus to Christ’s finished work (Romans 5:8-10).

• The Spirit testifies with our spirit that we are God’s children (Romans 8:16).

• Confession and repentance restore fellowship, not sonship (1 John 1:9).


Summary Encouragement

1 Corinthians 15:2 points away from self-effort to the objective gospel. Assurance flourishes as believers keep holding the unchanging message of Christ’s death and resurrection, trusting the God who both secures and sustains their salvation.
