Vatican City, Oct 10, 2014 / 06:57 am (CNA/EWTN News).- In his homily on Friday Pope Francis encouraged faithful to guard their hearts by doing a daily examination of conscience, saying that we if we don't, we risk letting the devil in rather than the Lord.

“Guard the heart, as a house is guarded, with a key. And then watch the heart, like a sentinel: How often do wicked thoughts, wicked intentions, jealousy, envy enter in?” the Pope asked his Oct. 10 Mass attendees.
