who turn back to destruction

A person who loses courage and faith are spoken of as if he were stepping back in fear from something. And "destruction" is spoken of as if it were a destination. Alternate translation: "who stop trusting God, which will cause him to destroy us" (See: rc://en/ta/man/translate/figs-metaphor)

for keeping our soul

Living eternally with God is spoken of as if it were keeping one's soul. Here "soul" refers to the whole person. Alternate translation: ", which will result in us living with God forever" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-synecdoche)
