(cont'd)...
Now we receive the Holy Spirit through faith in Jesus Christ (Galatians 3:14) and if we have been given the Holy Spirit, we obey Him (Acts of the Apostles 5:32).
There is more to that passage.
Rom 8:9, But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
Rom 8:10, And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
Rom 8:11, But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Rom 8:12, Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
Rom 8:13, For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
Rom 8:14, For as many as are led by the Spirit of God, they are the sons of God.
In v. 12, it should be clear that if you have the Holy Spirit, you are not obligated to walk after the flesh and it may even be that you owe it to God to walk according to the Spirit.
Here is another passage that is of relevance.
Gal 5:16, This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Gal 5:17, 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.
Gal 5:18, But if ye be led of the Spirit, ye are not under the law.
Gal 5:19, Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
Gal 5:20, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Gal 5:21, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Gal 5:22, But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
Gal 5:23, Meekness, temperance: against such there is no law.
This passage tells us what it means to walk not after the flesh but after the Spirit; and it is a companion passage to Romans 8:1-14; which we have shared above.
