Romans 8:5-6, 13

For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit. For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace.

For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.
