The King and His Kingdom and the Mystery - Marianne Manley

The timeline embedded in the order of the books of the Bible is explained.
Jesus Christ spoke to Israel,
Peter spoke to Israel,
Paul spoke to all now,
Hebrews will speak to Israel.
We cannot mix the gospel of the kingdom with the gospel of the grace of God, we cannot mix Peter and Paul, and we cannot mix Christ's instructions to His earthly group with Christ's instructions to His heavenly group.
