Romans 8:6-8

Now the mind of the flesh is death [both now and forever—because it pursues sin]; but the mind of the Spirit is life and peace [the spiritual well-being that comes from walking with God—both now and forever]; the mind of the flesh [with its sinful pursuits] is actively hostile to God. It does not submit itself to God’s law, since it cannot, and those who are in the flesh [living a life that caters to sinful appetites and impulses] cannot please God.
