1 Peter 1:9

9Receiving the end of your faith He reminds the faithful where they ought to direct all their thoughts, even to eternal salvation. For this world holds all our affections ensnared by is allurements; this life and all things belonging to the body are great impediments, which prevent us from applying our minds to the contemplation of the future and spiritual life. Hence the Apostle sets before us this future life as a subject of deep meditation, and he indirectly intimates that the loss of all other things is to be deemed as nothing, provided our souls be saved. By saying receiving, he takes away all doubt, in order that they might more cheerfully go on, being certain of obtaining salvation. (14) In the meantime, however, he shews what the end of faith is, lest they should be over-anxious, because it is as yet deferred. For our adoption ought now to satisfy us; nor ought we to ask to be introduced before the time into the possession of our inheritance. We may also take the end for reward; but the meaning would be the same. For we learn from the Apostle’s words, that salvation is not otherwise obtained than by faith; and we know that faith leans on the sole promise of gratuitous adoption; but if it be so, doubtless salvation is not owing to the merits of works, nor can it be hoped for on their account.

But why does he mention souls only, when the glory of a resurrection is promised to our bodies? As the soul is immortal, salvation is properly ascribed to it, as Paul sometimes is wont to speak, —

“That the soul may be saved in the day of the Lord.”
(1 Corinthians 5:5.)

But it is the same as though he had said “Eternal salvation.” For there is an implied comparison between it and the mortal and fading life which belongs to the body. At the same time, the body is not excluded from a participation of glory when annexed to the soul.
