Greek: 'karpophoreo' ^2592^, "to bear or bring forth fruit" , is used (a) in the natural sense, of the "fruit of the earth," <Mark 4:28>; (b) metaphorically, of conduct, or that which takes effect in conduct, <Matt. 13:23; Mark 4:20; Luke 8:15; Rom. 7:4,5> (the latter, of evil "fruit," borne "unto death," of activities resulting from a state of alienation from God); <Col. 1:6> in the middle voice; <Col. 1:10>.#
Note: For "bring forth fruit to perfection (maturity)," <Luke 8:14>

The main positive use in the New Testament is.... "that you may have a walk worthy of the Lord, fully pleasing Him, being fruitful in every good work and increasing in the knowledge of God;"
Colossians 1:10 (NKJV)
(NB. The good work is NOT THE FRUIT, but we are to be 'fruitful IN EVERY GOOD WORK' (our motive/ character etc..)).
In Galatians 5:22, fruit is 'karpos' which is the root of the above.
