As illustrated by the readings for the 13th Sunday in Ordinary Time, God is the source of all goodness, including the gift to recognize that all good things that surround us come from God. The desire to share with others the gifts He has so graciously shared with us also comes from God.
In the letter to the Corinthians, Paul addresses a group of Christians who have received an overabundance of spiritual gifts. In addition, they are doing well financially.
