The provocative title is true and intended to get your attention. Simply, the New Covenant is NOT with the Gentiles. That is not to say Gentiles can’t enter in, because Ephesians 2 and Romans 9-11 teach that they can, however, they immediately stop being Gentiles and become a part of Israel.
Until one understands this and the attendant implications (Torah to be written on their heart), they simply do not understand Scripture nor can they correctly assemble prophecy. Hard to swallow, I know.
Study it out. How many eternal promises are there to Israel? To the ‘house of Israel?’ To the ‘house of Judah?’ To ‘Ephraim?’
Christian doctrine ignores these glaring pieces precisely because they do no understand them. I was a pastor. Seminary trained. I nor my professors understood these things, yet in His mercy, Abba is restoring the ancient paths (Jer. 6:16-19) and recovering His flock.
Dare to ask God to open your eyes to ALL of His Word.
