No it doesn't. Obedience and endurance ensure salvation
In your endurance you possess your souls. Luke 21:19
Your reply—
“Obedience and endurance ensure salvation. In your endurance you possess your souls” (Luke 21:19)—is taking a verse from a tribulation context and applying it to justification,

which mixes categories that Scripture keeps distinct.
That verse (Luke 21:19) is spoken by Jesus in the context of
tribulation perseverance, not justification. He’s exhorting His disciples to remain steadfast during persecution so they might
preserve their lives (“souls”) through endurance—not to teach that endurance
earns salvation.
Paul’s flow in Romans 5 makes the distinction clear:
“Therefore being justified by faith, we have peace with God through our Lord Jesus Christ… being reconciled, we shall be saved by His life.”
— Romans 5:1, 10 (KJV)
Justification brings reconciliation; reconciliation guarantees ultimate salvation.
Obedience and endurance are
fruits of that salvation, not
conditions for earning it.
Ephesians 2:8–10 affirms the same order:
- Grace through faith — the means of salvation (v. 8–9)
- Good works — the result and evidence of salvation (v. 10)
So endurance is the
evidence that one truly possesses saving faith (cf. 1 John 2:19), not an additional requirement that replaces grace.
Luke 21:19 is part of Jesus’
Olivet Discourse (Luke 21:5–36), where He warns His disciples about:
Coming persecution,
Jerusalem’s destruction, and
The trials preceding His return.
So the verse doesn’t describe how to
gain eternal life but how to
endure faithfully through coming hardship.
The Greek literally reads:
“By your endurance, you will gain your lives.”
(Ὑπομονῇ ὑμῶν κτήσασθε τὰς ψυχὰς ὑμῶν)
- “Patience” (ὑπομονή) means steadfast endurance under pressure — remaining faithful when tested.
- “Possess” (κτάομαι) means to gain, preserve, or win something.
- “Souls” (ψυχή) can mean life, person, or inner being.
Thus, Jesus is saying:
“By patient endurance, you will preserve your life — you’ll stay spiritually safe and secure through trial.”
It’s a call to
faithful perseverance, not
works-based salvation.
This verse aligns with the broader biblical theme:
True believers
endure because they are genuinely saved (Matthew 24:13, John 10:27–28).
Endurance is
evidence of saving faith — not the means of earning it.
In other words:
Perseverance does not cause salvation; it confirms it.
Jesus was telling His followers:
“When the world falls apart and persecution comes, don’t panic or give up. Keep trusting Me. In that endurance, you will preserve your true life — your soul.”
Grace and Peace
