New Creation
The “new or fresh creation” (kaine ktisis[kainov”ktivsi”]) occurs twice in the New Testament (2 Cor 5:17; Gal 6:15). It is the renewal of creation it will be helpful to consider this background before attempting to explain in its new form.
Renewal in Isaiah. In the latter half of Isaiah (42:9; 43:18-19; 48:6; 65:17-25; 66:22) the prophet declares that God is about to do something new (42:9; 43:18-19; 48:6). Salvation is described along the lines of a new exodus (“I am making a way in the desert and streams in a wasteland, Isa 43:19), and what God is about to do will completely surpass old categories (“new things, hidden things unknown to you. They are and will be created. You have not heard of them before today, 48:6b-7). This declare the promise of The Highest intervention to bring his people and creation into a new thing.
We can see, now, many new things that Isaiah and that generation did not experience. What about spiritual things? Yahoshua the Nazoraion or Nzr Olam brought us. A way to follow the Way in the dessert, that is the Holy Spirit in the fullness has been offered to all. John 1:16
