The Word became flesh. "We got to heaven when we die" isn't wrong, it's just not big enough. The Kingdom of God is ALREADY inaugurated through the life, death, resurrection, and ascension of Jesus, who is the perfect human imager and King. But, the kingdom of God is not yet here in its fulness as we await it's consummation at the 2nd coming of Christ when He restores all of creation. we live in the overlap of these two realities.
