GALATIANS 5:16
This I say then, WALK IN THE SPIRIT, and ye shall not fulfil the lust of the flesh.

A lot of times when believers talk about walking in the Spirit, they sort of get misty-eyes and foggy-headed. They seem to think that walking in the
Spirit is some kind of mystical experience where they just sort of float around caught up in the Holy Spirit.

But really walking in the Spirit is very simple. Walking in the Spirit is walking in the fruit of the spirit. Walking in the Spirit is walking in love.
Notice what Paul says about walking in the Spirit. First he lists works of the flesh. Then he lists the fruit of the spirit.
Galatians 5:16,18-25 (KJV)

16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.

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

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.

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.

Paul said, "Now the works of the flesh are manifest . . ." (v. 19). Or we could say it this way: "If you walk in the flesh, then the works of the flesh will be manifested, and they will dominate you."
Notice what Paul says about walking in the Spirit: "This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh" (Gal. 5:16).

Well, how do you walk in the Spirit? To walk in the Spirit is to walk in the fruit of the spirit. To walk in the Spirit is to walk in love! In other words, walking in the Spirit is walking in love , joy, peace, longsuffering, gentleness, goodness, faith, meekness, and temperance.

Then Paul says, " . . . against such there is no law. " In other words, when you are walking in the fruit of the spirit, there is no law that can bear witness against you because you will be fulfilling all the requirements of the law.

So putting it simply, we can say that to walk in the Spirit is to walk in the nine fruit of the recreated human spirit. That is the essence of what walking in human spirit is all about.
