he is a new creation

Alternate translation: "he is a new person". Paul speaks of the person who believes in Christ as if that person were a new person that God had created. The old and new creation probably refer to how Paul illustrates the old and new self.

The old things have passed away

Here "the old things" refers to the things that characterized a person before he trusted in Christ.
