In John 15, we read about abiding in the Vine and the Vine bringing forth fruit in our lives.
The word "fruit" is translated from the Greek word
karpos.
Here is what HELPS word-studies says about
karpos:
2590 karpós – properly, fruit; (figuratively) everything done in true partnership with Christ, i.e. a believer (a branch) lives in union with Christ (the Vine). By definition, fruit (2590 /karpós) results from two life-streams – the Lord living His life through ours – to yield what is eternal (cf. 1 Jn 4:17).

As we abide in the Lord Jesus Christ, the Father carefully tends to our lives, cleansing us of the filth and impurity of this world, and the Lord Jesus Christ infuses our lives with His life.
Another thought --- what is the purpose of the fruit? Do we bear fruit only for ourselves? Or do we bear fruit for the Lord Jesus Christ?
We bear the fruit of our Lord Jesus Christ so that others may see and be drawn to our Lord Jesus Christ. Then He can work in others to bring forth fruit to even more.
