But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control. Against such there is no law. Galatians 5:22-23 (NKJV)
Goodness: uprightness of heart and life, moral excellence (virtue), beneficence
Goodness goes beyond just being "good" or moral. It means that moral excellences translates into dong — beneficence, charity, making a contribution.
Notice the progression: what God prefers (love), grace recognized (joy), God's gift of wholeness (peace), and attitude of uncomplaining (longsuffering) is the foundation for our actions kindness (favorable attitude — that is serviceable) and now goodness (beyond being good — doing good).
Goodness, moral excellence that goes beyond just being — and translates into doing!
