In our readings, we hear of wisdom, and that is a virtue needed in to be stewards. Wisdom is to see as God sees, with an eternal perspective. We grow in wisdom by avoiding vice and going to the Sacrament of Reconciliation, prayer and adoration, reading of the lives and the writings of the Saints, and by remembering we become the average of the people we spend time with.
