The ability to love others unconditionally is certainly a fruit of the spirit. The Bible talks about love quite a bit, and it is clear, that one of the outward signs of spirituality is love. So is love something that can be measured as a fruit? Is it something that our ministry can produce?
I think the answer on both counts is no, not really. As far as measurement goes, outward displays can be motivated selfishly – only God knows the intentions and the motivations of the heart. And for production, again, we really rely on the Holy Spirit to transform hearts to produce love.
So what can a ministry do? How can a ministry be organized to produce or to optimize love as an output?
I think that the best we can do with the personal fruits of the spirit (peace, love, joy, etc) are to model them. That is, our most mature members should be the example that other, less mature brothers and sisters need so that they can see, feel, and smell what these fruits are.
In order for this to happen, we must organize our ministry, so that as many of our new and immature believers have opportunity to spend time with more mature believers, both working side by side in ministry and getting close to them in social settings. Mature believers must understand that it is their role and responsibility to encourage newer, less mature believers by being an example.
