1 Peter 1:9

Receiving--in sure anticipation; "the end of your faith," that is, its crowning consummation, finally completed "salvation" (Peter here confirms Paul's teaching as to justification by faith): also receiving now the title to it and the first-fruits of it. In Pe1 1:10 the "salvation" is represented as already present, whereas "the prophets" had it not as yet present. It must, therefore, in this verse, refer to the present: Deliverance now from a state of wrath: believers even now "receive salvation," though its full "revelation" is future. of . . . souls--The immortal soul was what was lost, so "salvation" primarily concerns the soul; the body shall share in redemption hereafter; the soul of the believer is saved already: an additional proof that "receiving . . . salvation" is here a thing present.
