Isn't that convenient? Doesn't this ring a bell? This is itching ears theology, that is all dispensationalism is. Church gets a free ride, no one else does. This is why you MUST reject dispensationalism and preferably any other isms.
I agree that the dogma of dispensationalism is not defensible, except for these periods:
1. Before creation God was unknown by humans.
2. From creation until Abraham God was revealed to humans solely via general revelation.
3. From Abraham until John the Baptist, God's will was revealed to the Jews via Moses and prophets.
4. From Jesus until Judgment Day God is most fully revealed to humanity by the NT.
5. From resurrection to heaven throughout eternity God will be as fully known as possible by all of God's spiritual children.
