Where the power of evangelization comes from...

“‘Converts were, and still are, acquired through the prayer and sacrifice of unknown faithful. Christ won souls, not by the power of his marvelous speeches, but rather by the power of his constant prayer. He preached by day, but by night he prayed’ Souls—that is to say, living people—cannot be brought over to God just by persuasion or discussion. They want to be asked of God in prayer, for God. … We finally have to learn again that we need less discussion and more prayer.”
