By Archbishop Charles Chaput, Archdiocese of Philadelphia - As with the persons we love, so with God. We can teach about God with eloquence and grace; we can pour all our strength into helping the poor; we can sing his praises with golden tongues – but unless we give our hearts to him in the habit of silent prayer, listening for his voice and placing ourselves in his presence again and again, whether we feel like it at the moment or not, then our faith is just an empty shell.
