Elsewhere in the New Testament the Spirit's activity within believers has to do with fruit and gifts. The fruit of the Spirit is the effect of the Spirit upon the believer's character. The fruit of the Spirit, say the apostles, is love, joy, peace, patience, faithfulness, self-control, and so on. The fruit of the Spirit is the fruitfulness of the presence and power of God. To be sure, some people are more patient than others by nature, more patient than others simply by genetic coding.
Some people are cheerier than others, or more self-controlled than others, simply by nature.
But regardless of what we are by nature, there is a transformation wrought by the Spirit that transcends natural endowment. The apostle Paul contrasts the fruit of the Spirit with the works of the flesh. The works of the flesh are fornication, idolatry, jealousy, selfishness, etc. The fruit of the Spirit , however, is precisely what God alone can effect in us. The fruit of the Spirit is the fruitfulness of that Spirit now rooted ever so deep in us and suffusing us throughout.
