1 “There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.”
2 “For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.”
We are not to walk after the ways of flesh as it is corruptible and leads us to sin. The flesh tells us we need this or that to be happy. Yet, if we focus on the spiritual aspect, if we can bring our minds completely to that realm so much of the fleshly desires melt away and do not become tempting to us.
