What does the Bible say about goodness?

In Ephesians 5:9-14, we are told that the fruit of the Spirit encompasses goodness, righteousness, and truth. True goodness is a quality only possessed by God; He is the judge of goodness, and in His eyes, there is none good, no not one (Romans 3:10). We cannot produce goodness ourselves, as our hearts are deceitful and desperately wicked (Jeremiah 17:9). The goodness of God is demonstrated through His grace and is revealed in the person and work of Jesus Christ, our only hope for showing forth goodness acceptable unto the Lord.
