Albert Barnes on 1 Peter 1:9

Receiving the end of your faith, even the salvation of your souls. The result or object of your faith; that is, what your faith is designed and adapted to secure. Rom 10:4. The word rendered receiving is used here as indicating that they would surely obtain that. They even now had such peace and joy in believing, that it furnished undoubted evidence that they would be saved; and such that it might be said that even now they were saved. The condition of one who is a true Christian here is so secure that it may even now be called salvation.
