Matthew 24:13 But he that shall endure unto the end, the same shall be saved.

Saved from what? The passage doesn't even mention Hell or sins. It is talking about being saved from death during the Tribulation period - ie. physical deliverance, not spiritual. Jesus was speaking to saved people during the Tribulation, and was telling them if they persevered, they would live to see His return - otherwise they would be martyred under the antichrist's persecutions or during some of the afflictions of the Tribulation period.

For those who want to argue that saved must always be referring to spiritual salvation - ie. from sins or from Hell - read this verse:

Psalms 18:3 I will call upon the LORD, who is worthy to be praised: so shall I be saved from mine enemies.

Context determines what type/kind of salvation is in view.
