In all of Paul’s writings his apocalyptic mindset comes through. He relates how God broke in and changed the course of human history. I cannot help but relate this to my research paper on adoption in Ephesians 1:5. Paul talks about how God redeems his church through the act of adoption, which is a conscious breaking into of human events by God. But if we were to view Paul’s writings through the apocalyptic style, especially in the Jewish vein, then this description does not fit really into Paul, except for that one example you cited above in Thessalonians.
