I think he is right. If we DO NOT produce fruit then we are not really known as to who we belong to, God or satan. As Jesus cursed the olive tree because it did not bear fruit I think those that never bring forth their fruit he will cast them out because not only did they, obviously, never know Him but he does not know them. So therefore if you want to make it in you better produce some fruit so God knows you are His. (not that he really needs you to but by producing fruit EVERYONE else knows you are His)
does that make any sense?
I was getting more to the "we must produce" the fruit. I'm not sure I believe that the "gifts" have anything to do with producing the "fruit" in us. I'm not sure that "we" produce the fruit. I believe that the Holy Spirit produces that fruit in us which then conveys to a lost world.
The fruits of the spirit aren't the same as the fruits of our labor for Christ such as winning souls and accomplishing things for Kingdom of God. I don't see that we "produce" the fruits of the spirit.
I guess it probably comes down to how we're defining "produce".
