Operating in the flesh is death. So, put on the new self – always!
The flesh is everything that operates in the tree of the knowledge of good and evil; the self-denominated legacy of fallen man.
Romans 8:5-14 (NASB) reads:
5 For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit.
6 For the mind set on the flesh is death, but the mind set on the Spirit is life and peace,
7 because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so,
8 and those who are in the flesh cannot please God.
9 However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him.
10 If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness.
11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
12 So then, brethren, we are under obligation, not to the flesh, to live according to the flesh–
13 for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live.
14 For all who are being led by the Spirit of God, these are sons of God.
Be therefore renewed in the spirit of your mind; putting on the new self that has been created in YHWH.
Ephesians 4:22-24 (NASB) reads
22 that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit,
23 and that you be renewed in the spirit of your mind,
24 and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.
Be blessed to be a blessing.
