The essence of who we are in this world. In Romans 8:1-26, the verses here talk about the sins of flesh. Not necessarily meaning the body itself but rather the temptations of being in our physical bodies. The spirit is there to help guide us beyond those temptations. Galatians also talks about the lust of the flesh and to choose to live and walk in the Spirit.
Proverbs 17:22
A merry heart doeth good like a medicine: but a broken spirit drieth the bones.
1 Corinthians 3:16-17
16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
Galatians 5:16-17
16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Galatians 5:22-25
22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23 Meekness, temperance: against such there is no law.
24 And they that are Christ's have crucified the flesh with the affections and lusts.
25 If we live in the Spirit, let us also walk in the Spirit.
