God in Jesus brings in the new creation, and this new creation is a remaking of the old creation in its entirety. Of course humans are at the pinnacle of creation, made in God's image, and in the Incarnation, God becoming human in the unique person of Jesus.
We humans in Jesus are both recipients and agents of this new creation in the world. God uses us in living out and proclaiming Jesus and the kingdom, in the good news that is brought, that Jesus in his death and resurrection is declared to be Lord over all, to begin to impact all things now. All enemies will by and by be put under Jesus' feet, ending with the last enemy, death.
I often wonder how this is worked out, and certainly at the heart of it is the conversion of others to Jesus. But all the works we in Jesus do, are meant by the Spirit to have God's stamp on them, the stamp and act of new creation. A work of God, yet we are involved in that work.
Any thoughts here that might help us?
