Yes, the kingdom of God is here, right now, co-existing besides all the other stuff that this fallen world includes. It’s within us, but there is other stuff there too. It’s deep inside us, but we are covered with layers of dragon scales, just like Eustace in the Narnia tale, who became a dragon because of his sinful egotism. Then Aslan (who represents Jesus in the books) came and tore off the skin, one layer at a time, when Eustace repented with remorse. It was painful, but after it was done, Eustace was himself again. That symbolized something we all must do.
