1 Peter 1:6

“Wherein ye greatly rejoice, etc.] The Vulgate Latin version reads, “in which ye shall rejoice”: and so the Syriac version, adding, “for ever”; and refer these words to the “last time”; or, times spoken of in the preceding verse; when the saints will greatly rejoice, being in full possession of eternal salvation; in distinction from the present time, in which they are in heaviness; but it is better to read the words in the present tense, and as expressive of the saints in this life, who are blessed with that fruit of the Spirit, joy, and have always reason to rejoice, and greatly rejoice.
