To bear fruits means we are to become virtuous. If we are living our lives the way God intends, then we would produce the fruits of the Holy Spirit which are love, joy, peace, patience, kindness, generosity, faithfulness, gentleness, self-control (see Galatians 5:22-23). The Catechism of the Catholic Church teaches that, “The fruits of the Spirit are perfections that the Holy Spirit forms in us as the first fruits of eternal glory” (CCC 1832). Therefore, God is leading us to a first taste of heaven.
