1-е Петра 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.

The apostle describes the persons to whom he writes, and salutes them (Pe1 1:1, Pe1 1:2), blesses God for their regeneration to a lively hope of eternal salvation (Pe1 1:3-5), in the hope of this salvation he shows they had great cause of rejoicing, though for a little while they were in heaviness and affliction, for the trial of their faith, which would produce joy unspeakable and full of glory (Pe1 1:6-9). This is that salvation which the ancient prophets foretold and the angels desire to look into (Pe1 1:10-12). He exhorts them to sobriety and holiness, which he presses from the consideration of the blood of Jesus, the invaluable price of man's redemption (Pe1 1:13-21), and to brotherly love, from the consideration of their regeneration, and the excellency of their spiritual state (Pe1 1:22-25).

1:9 salvation of your souls: The Greek word translated souls often refers to the whole person and not just to some part or aspect of the person (Matt 20:28; Mark 8:35). Salvation affects our whole person, not the inner person only.
