Hi Mooky,
As a believer, we all have the fruit of the Spirit. As we grow, learn and are transformed by the renewing of the mind, we learn what it means to walk in the Spirit and not fulfill the lusts of the flesh. We continue to put off that old man and walk in the new man instead.
Paul says to walk in the Spirit so if we are walking in the Spirit we are bearing fruit.
Ephesians 5:8-10
.....for you were formerly darkness, but now you are Light in the Lord; walk as children of Light (for the fruit of the Light consists in all goodness and righteousness and truth), trying to learn what is pleasing to the Lord.
