Matthew 24:13 - Ellicott's Commentary On The Whole Bible

He that shall endure unto the end ... — The words have at once a higher and lower sense. Endurance to the end of life is in every case the condition of salvation, in the full meaning of the word. But the context rather leads us to see in the “end” the close of the period of which our Lord speaks, i.e., the destruction of Jerusalem; and so the words “shall be saved” at least include deliverance from the doom of those who were involved in that destruction.
