Romans 8:4-6

so that the [righteous and just] requirement of the Law might be fulfilled in us who do not live our lives in the ways of the flesh [guided by worldliness and our sinful nature], but [live our lives] in the ways of the Spirit [guided by His power]. For those who are living according to the flesh set their minds on the things of the flesh [which gratify the body], but those who are living according to the Spirit, [set their minds on] the things of the Spirit [His will and purpose]. 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]
