We were therefore buried with him through baptism into death in order that,  just as Christ was raised from the dead through the glory of the Father, we too may live a new life.

Here we see it clearly, this new life is first of all spiritual.  No longer slaves to sin and tied to the world, we enter a life where God is the center and as that new God-life grows in us toward holiness, our physical and mental life changes as well.  Harsh reactions to people and events soften, modesty and kindness become the norm.  Love and grace vault to the forefront of our daily lives.
