Can you lose your salvation? (assurance + eternal security)

Q: Can you lose your salvation? (assurance + eternal security)

This is a question sincere Christians answer differently, so the honest answer shows the major views with their key texts and endorses none. What nearly all agree on first: - Assurance is possible — John wrote 'that you may know that you have eternal life' (). - Salvation is by grace, and God is faithful to His own (). - Believers are called to continue in faith, not to treat grace as license. The disagreement is over whether a true believer can finally fall away and be lost. Two main positions (with a common third nuance) are laid out below.

Short answer

This is a question sincere Christians answer differently, so the honest answer shows the major views with their key texts and endorses none. What nearly all agree on first:

Assurance is possible, John wrote 'that you may know that you have eternal life' (1 John 5:13).
Salvation is by grace, and God is faithful to His own (Philippians 1:6).
Believers are called to continue in faith, not to treat grace as license.

The disagreement is over whether a true believer can finally fall away and be lost. Two main positions (with a common third nuance) are laid out below.

Question

Can you lose your salvation? (assurance, eternal security, and the different views)

Analysis

The main views

View	Position	Key texts	Held by
Eternal security / perseverance ("once saved, always saved")	A true believer is eternally secure, kept by God's power and cannot finally be lost; those genuinely born again will persevere.	John 10:28; John 10:29; Romans 8:38; Romans 8:39; Philippians 1:6; Ephesians 1:13; Ephesians 1:14	Reformed/Calvinist; many Baptists
Conditional security	Salvation can be forfeited through settled unbelief or apostasy; the Bible's warnings against 'falling away' are real possibilities, not hypotheticals.	Hebrews 6:4; Hebrews 6:6; Hebrews 10:26; Galatians 5:4; 2 Peter 2:20; 2 Peter 2:21	Arminian/Wesleyan; Catholic; Orthodox

The common nuance

Many in the 'security' camp add an important qualifier from 1 John 2:19: those who fall away and never return 'went out from us, but they were not of us', i.e., their leaving showed they were never truly regenerate, rather than that they lost a real salvation. On this reading the warnings (Hebrews, etc.) are one of the means God uses to keep true believers persevering. The 'conditional' camp reads the same warnings as genuine cautions to real believers. Both sides therefore take the warning passages seriously; they differ on what the warnings prove.

Where the sides converge

All agree that presumption is dangerous and assurance is real: salvation rests on Christ's finished work, not on our performance (Ephesians 2:8; Ephesians 2:9), and yet genuine faith continues and bears fruit (Colossians 1:23; Hebrews 3:14). Practically, both counsel the same thing, keep trusting Christ, and let assurance rest on Him.
