The Spiritual Incentives
The Fruits of the Spirit are The Universal Laws personally applied. When the Universal Laws are sufficiently realized they become the Gifts of the Spirit. These are highly personalized and can be Spirit communication, Healing ability, and Prophetic ability as well as Faith that moves mountains and other miraculous powers. They can also be increased ability with more familiar talents such as:
Leading/Administrating Diligently
and myriads of other things.
In addition to these the Workings of Miracles, Different Kinds of Tongues, and Interpretation of Tongues are also mentioned in 1 Corinthians 12.
All of these are accompanied by love.
