Dallas Willard (1935-2013) author and professor wrote:
“Outwardly, life in the Spirit manifests itself in two ways. Gifts of the Spirit will enable us to perform some specific function—such as service or healing or leading worship—with effects clearly beyond those of our own making. These gifts serve God’s purposes among His people, but they do not necessarily signify the state of our heart.
The fruit of the Spirit, in contrast, gives a sure sign of transformed character. When our deepest attitudes and dispositions are those of Jesus, it is because we have learned to let the Spirit foster his life in us. Paul confessed, “I have been crucified with Christ; and it is no longer I who live, but it is Christ who lives in me” (Galatians 2:19–20). The outcome of Christ living within us through the Spirit is fruit: “love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, and self-control” (Galatians 5:22–23; see also John 15:8).
“When the Spirit of truth comes, he will guide you into all the truth, for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. He will glorify me, for he will take what is mine and declare it to you. All that the Father has is mine; therefore I said that he will take what is mine and declare it to you.” Jesus
