Leonard Goppelt wrote a gem of a commentary on 1 Peter. Â I’ve been studying it as I prepare to exhort on the amazingly redemptively-historical 1 Pet 1:10-12. Â Here is a typical quote from Goppelt on the text:
Prophecy enables the Church to understand the Christ-event preached to it as fulfillment, as eschatological salvation, and, therefore, to appropriate proclamation as gospel.
It makes the biblical-theological heart warm, doesn’t it?

I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
