1. We are reading a letter written by Peter to The Dispersion about 2000 years ago.
2. By inspiration of The Holy Spirit, Peter told The Dispersion the following;
a. Your conduct will cause The Nations to glorify God
b. This was to occur during the day or in a day of visitation or inspection
The context denotes the timing of this event during the lifetime of The Dispersion. WE ARE NOT interested in “THE HOW” of the matter, this is the ambiguous part of the context. The unambiguous portion is the proclamation to the relevant audience which denotes the timing. Therefore, it CANNOT go outside the lifetime of The Dispersion to whom the letter was written to, UNLESS...
You can show where in the context does it speak to another people, place and time far removed from the original audience making THIS proclamation meaningless to The Dispersion?
Your understanding of 1 Peter seems strange to me. Peter has much to say to Christians about how they should live and that this lifestyle would be a witness to the gentiles. Why is it you think this reaction by the gentiles Peter speaks of had to take place in 70AD? And the Greek word translated "glorify" is an aorist subjunctive which carries a bit of doubt or uncertainty. Seems to me Peter is speaking of behavior in the future that
may (this word is not in the Greek but speaks of uncertainty in our translations) happen in some cases or might not.
Here is a fine example of what I believe Peter was speaking about: Julian the Apostate, recognizing the behavior of Christians, exclaimed "These impious Galileans feed not only their own poor, but ours as well". Now there is something to be excited about. And this statement was made hundreds of years after Peter wrote, and is a fine example of fulfillment of Peter's prophecy.
I'm curious why you would think that the timing does not apply to us but the instructions Peter gave in his letter would apply? Or do you see the time of visitation as an ongoing thing?
