Charles Ellicott Commentary Romans 8:6

"For the mind of the flesh is death; but the mind of the Spirit is life and peace:" — Romans 8:6 (ASV)

Translate, For the mind of the flesh is death, but the mind of the Spirit is life and peace. To think of nothing but the gratification of the senses is in itself death—that dead condition of the soul which issues in eternal death; and, on the other hand, to have the thoughts and affections governed solely by the Spirit brings with it that healthful, vital harmony of all the functions of the soul which is a sure pledge and foretaste of a blissful immortality.

Death and life are here, as elsewhere, most frequently in St. Paul, neither spiritual death and life alone, nor eternal death and life alone, but both combined. The Apostle does not here draw any distinction between the two things.
