ISB ~ 1 Peter 1 v9

the outcome:Salvation is here described as a future event, which means it cannot be reduced to an event or experience already completed in the past. See note on Rom 5:10.

salvation of your souls:The expression is a Semitic way of saying “your salvation”. The term “soul” is used in the Hebrew sense of a whole living “person” (as in 1 Pet 3:20).
