Matthew 24:13

13. Shall endure unto the end This is essentially the same end as is specified in the inquiry, namely, the end of the world. For he who endures through the day of his probation endures to the judgment day. Shall be saved Not from the destruction of Jerusalem, but from the condemnation at the judgment. This is giving the words precisely the same meaning as in Matthew 10:22, where see note. Luke here adds, in view of the persecutions described in this paragraph: “But there shall not a hair of your head perish.” This cannot mean that none of them should be slain, for it is expressly said in Matthew 24:9, “They shall kill you.” But the dying martyr, under the express guidance of God, and with the certainty that heaven sees it good, is not perishing. And the reason why the martyr does not perish, and why he may possess his soul in patience, even in the midst of martyrdom, is given in the following verse, namely, his death is the source of triumph to the cause for which he chooses to die.
