Dallas Willard (1935-2013) wrote, “The fruit of the Spirit simply is the inner character of Jesus himself that is brought about in us through the process of Christian spiritual formation. It is the outcome of spiritual formation. It is “Christ formed in us.” It is called “fruit” because, like the fruit of trees or vines, it is an outgrowth of what we have become, not the result of a special effort to bear fruit. And we have become “fruitful” in this way because we have received the presence of Christ’s Spirit through the process of spiritual formation, and now that Spirit, interacting with us, fills us with love, joy, peace…”
“So, every healthy tree bears good fruit, but the diseased tree bears bad fruit.
A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit.” Jesus
