This, I think, is the gist of it when it comes to our role in the new creation, what it means for us to be in, and help build the kingdom of GOD:

“Every act of love , gratitude and kindness; every work of art or music inspired by the love of GOD and delight in the beauty of his creation; every minute spent teaching a severely handicapped child to read or walk; every act of care and nurture, of comfort and support, for one’s fellow human beings, and for that matter one’s fellow non-human creatures; and of course every prayer, all SPIRIT-led teaching , every deed which spreads the gospel, builds up the church, embraces and embodies holiness rather than corruption, and makes the name of JESUS honoured in all the world - all of this will find its way, through the resurrecting power of GOD, into the new creation which GOD will one day make. That is the logic of the mission of GOD.”
