Matthew Poole and continuators on 1 Peter 1:9

9 Receiving the end of your faith, even the salvation of your souls .

Either this word is to be taken improperly, and by an Enallage, the Future being put for the Present Tense, q. d. being about to receive; or rather properly in the Present Tense, and then it intimates the certainty of the thing spoken of.

i. e. The Scope to which Faith tends, or the Reward of Faith.

Either, 1. Salvation more generally taken, which is begun in this Life, Ephes. 2.8. Tit. 3.5. or rather, 2. complete final Salvation in the other, as v. 5. and then the Sense is, either ye rejoice that ye shall certainly receive the full Salvation of your Souls, or ye rejoice that ye do receive that Salvation, viz. in the Promises of it, in those Graces of the Spirit wrought in you, which begin this Salvation, and are the Pledges of it, and in the certain Assurance of it.

i. e. (By an usual Synechdoche) the Salvation of your persons.
