Gal 5:16-17   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.

     To 'Walk in the Spirit' is to listen to Christ and His Word as guided by The Holy Spirit. One must first accept Christ to do this, and then understand His Word in 'newness'. It means to stop listening to every little urge of the flesh and seek our Saviour with understanding. Transfer your interests away from flesh things (not completely; we still live in the flesh and have a job to do),

 and onto our Father and His Plan, seeking to serve Him through Christ. If you do that, in sincerity, then He will begin to 'renew' your mind in Him, and control over the flesh will get easier. These are not idle words I'm saying; many who once followed the world, but are now in Christ, can show outward proof of His Spirit by their fruits.

Gal 5:18   But if ye be led of the Spirit, ye are not under the law.

     God's Law is perfect, and our flesh cannot be perfect in it. But the inner spiritual part of us, as led by GOD's Spirit, when we stay with Him, can be 'mature' to God's Law. But our flesh is yet under God's Law, and our flesh will be punished when we sin. Paul's going to make it clear for us:

Gal 5:19   Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20    Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
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.

     Notice verse 21 says those which do these such things 'shall not inherit the kingdom of God'. Can one who is guilty of such things turn away, change, and come to Christ, asking forgiveness and be saved? Isaiah 5:18 talks about those who love to sin, even pulling their sins around with a 'rope', kind of show and tell, hoping to teach others how to sin also. Those don't seek Christ, don't care if they sin or not, murder, etc., so what do you think? Our Father told us how to handle those which do great abominations, such as murder, and as I said before, that's where the death penalty came from, i.e. God's Law. Thus, God's Spirit is not behind any of the above 'works of the flesh'.

Gal 5:22   But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23    Meekness, temperance: against such there is no law.

     These are all 'fruit' of God's Spirit. None of these 'fruits' of God's Spirit are against His Law. So then, if we Walk in Christ, and not of the flesh, our works and fruit is not bound by God's Law. That's what Paul means by not being 'under the law'. So there is a 'condition' to be met. Those who teach that all of God's Law was fulfilled upon the cross, do so in error. If one goes out and steals something they'll soon find out just how The Law still applies.

Gal 5:24   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.
26    Let us not be desirous of vain glory, provoking one another, envying one another.

     To be in Christ is to overcome the flesh; it no longer controls our life, not being held in bondage by various vanities of the flesh. We may slip up at times, but our 'true heart' is towards Christ, and repentance is necessary to stay in His Grace.
     The other Message Paul is teaching about is vain glory. It's easy to look at the 'vain glory' of the world's ambitions for power, and try to apply those things to positions within Christ's Body. Each person in Christ has the 'gifts' which God furnishes to work His Plan. We are all equals in Christ as
