Which form ( or should I say style) of Dispensationalism do you mean? Scofield's? Ryries? Progressive? Pauline? Right now there are so many variations some of which would assert what you are declaring (Progressive) that to say that Ephesians defeats Dispensationalism would be discounted by C. Marvin Pate or Craig A. Blaising.

Because of this I would suggest you define your terms.

Peter

If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself. Augustine of Hippo
