The fruits of the Holy Spirit are, it seems to me, largely fruits of sustained interaction with God. Just as a child picks up traits more or less simply by dwelling in the presence of her parent, so the Christian develops tenderheartedness, compassion, humility, forgiveness, joy, and hope through "the fellowship of the Holy Spirit"--that is, by dwelling in the presence of God the Father and Jesus Christ his Son. And this means, to a very large extent, living in a community of serious believers.
