Just as into an empty church tower all sorts of animals , spiders, rodents , owls can entrench themselves , the same way the evil one can easily find a home in our empty hearts, unless its filled by the Holy Spirit . But as soon the bell , silent for a long time will ring out , it will banish everything from there that does not belong there , this is exactly what happens when prayer, the teaching of the gospel , the grace of the sacraments fill one’s life .
