'Preserve' in the Bible

And the disciples went and woke Him, saying, “Lord, save us, we are going to die!”

For whoever wishes to save his life [in this world] will [eventually] lose it [through death], but whoever loses his life [in this world] for My sake, he is the one who will save it [from the consequences of sin and separation from God].

Whoever seeks to save his life will [eventually] lose it [through death], and whoever loses his life [in this world] will keep it [from the consequences of sin and separation from God].

The Lord will rescue me from every evil assault, and He will bring me safely into His heavenly kingdom; to Him be the glory forever and ever. Amen.

But our way is not that of those who shrink back to destruction, but [we are] of those who believe [relying on God through faith in Jesus Christ, the Messiah] and by this confident faith preserve the soul.
