Yes, Paul is indeed a part of the BOC, and his preaching given to him directly from Christ is indeed for the BOC.
So are you not a believer with faith? Those things of which Jesus promised wasn't only to leaders, but to all. Please read the all-inclusive grammar in his words.
I have indeed. I serve Him with my all in the capacities He has empowered me. Do I fail at times...yes, as do we all. That's not an excuse, it's just the way it is.
Additionally, I'm the righteousness of God in Christ Jesus, so I don't have to worry about any greater righteousness in and of myself for I have no righteousness in and of myself, which is also true of us all. The righteousness imputed upon me is that of Christ Himself, covering me as it does for all the BOC.
However, those promises for miracles worked by all who were under the Kingdom Gospel, the promise made by Christ, was to another people at another time under another gospel that's no longer in force today because of the fall of Israel and the collapse of that middle wall of partition.
