Think of the greatest evangelists (e.g. St. Paul, St. Francis Xavier, or St Teresa of Calcutta) who changed thousands (some tens of thousands) of lives in their lifetimes. Amazing isn’t it? But, it is also a bit overwhelming, because this kind of evangelist is not common and most of us won’t ever be able to live up to such fruitfulness in our lifetimes. But, that isn’t the way in which the vast majority of Christians are called to be fruitful. It is a bit simpler than that.
