The New Testament makes a bold prediction related to unity – God will have a unified people from every tribe and tongue who are one and yet retain their diversity. This seems like an impossible prediction, but the Bible predicts it, the gospel makes it possible, and it is part of God’s plan to advance the gospel.
In the ascension of Jesus, mankind was put positionally over the powers of this age. This is why we are now in a great wrestle – not with men – but with the powers. Redeemed humanity is their greatest enemy because the only thing that empowers them is fallen humanity’s humanity’s submission to the powers and agreement with them is what has enabled them to stay in their place of authority.
