You need to stop posting until you actually know your Bible. This MAD stuff is perpetuated by the self-perception of 'authority' by just being able to post on the internet.
Oh, all this is prob that 'mystery' doctrine done wrong. The mystery is not the mission to the nations. It is that that mission would be powered by the Gospel, not the Law. Eph 3:5.
