(Mt. 24:13) Does this verse threaten eternal security?

CLAIM: Jesus said, “But the one who endures to the end, he will be saved” (Mt. 24:13). Does this mean that perseverance is necessary for salvation?

RESPONSE: Jesus may be referring to physical or bodily protection here. In Luke’s account, he writes, “Yet not a hair of your head will perish. 19 By your endurance you will gain your lives” (Lk. 21:18-19). This refers to physical protection. It’s also possible that Jesus is referring to spiritual salvation, in which he could be saying (1) believers need perseverance in the Tribulation, or (2) a true believer will always persevere.
