St. Alphonsus Liguori
“There it was also that St. Francis Xavier found refreshment in the midst of his many labors in India; for he employed his days in toiling for souls, and his nights in the presence of the Most Blessed Sacrament. St. John Francis Kegis did the same thing; and some times finding the church closed, he endeavored to satisfy his longings by remaining on his knees outside the door, exposed to the rain and cold, that at least at a distance he might attend upon his Comforter concealed under the sacramental species.”
