Having @Complete Chris's permission, here is an excerpt to start a thread on the ministry of Paul: The Two Ministries of Paul:- It is worth noting that the ministry of Paul at the time of the writing of Romans (during the Acts period) was indeed verifiable through recourse to the Old Testament Scriptures. Whereas, following the laying aside of Israel in unbelief at the end of the book of Acts (ch. 28), and the revelation of the mystery described in Ephesians chapter three, to Paul while in prison, no such verification could be made, for it was a new revelation, which had been 'hid in God' until the moment of it's revelation (Eph 3:9). Hence the desertion of Paul by, 'all they which are in Asia' (2 Tim 1:15). This further ministry of Paul, made known in the epistles written from prison (Ephesians, Philippians, Colossians, 1&2 Timothy and Titus) are separate and unique and should be compared with those written prior to that revelation, in order to try the things that differ: that we may be found to be faithful witnesses of the truth of God in this dispensation; and not found muddying the waters by the introduction of practices which apply to either the dispensations that are past, or those yet to come. Thank you Chris.
