From Wm. Kelly's "First Epistle of Peter," page 105.

" for the life of which the saint partakes was comparatively hidden from Old Testament believers; yet they had it in Him who had not yet appeared, but was truly hoped for. Now, since Christ came, this, and much more, is cleared up, and the believer is assured that he has it as a present thing, whatever be the added blessedness at His coming again, when the body is swallowed up by the life which the soul already has in Christ. For indeed it is life eternal, and so declared even now; and woe to him who is emboldened by the enemy to deny it!"
