The Bible describes the fruit of the Spirit as: love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control - Gal 5:22-23. The fruit of the Spirit is as a result of the workings of the Holy Spirit in the life of a believer. Just as the fruit of a tree will eventually be mature and seen, likewise the fruit of the Spirit must be cultivated in partnership with the Holy Spirit and will eventually be evident.
Contrast this to Gal 5:19-21 where the works of the flesh are listed: adultery, fornication, uncleanness, lewdness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries. If your life is governed by the flesh i.e. the natural way of doing things, then the works of the flesh will be evident in your life.
It takes the influence of the Holy Spirit to live a life that is not governed by the flesh. You must crucify the flesh and follow the guidance of the Holy Spirit. You crucify the flesh by resisting the temptations to fall into the behaviors and traps that lead to the works listed in Gal 5:19-21 and described in the second paragraph, with the help of the Holy Spirit. Then you position yourself to walk with the Spirit and His fruit by making the Word of God your standard.
