Two persons may live together for twenty-five years, for forty or for fifty years, and may still not be able to understand one another because of the lack of inner life; yet the inner life would enable them to understand one another in a moment. When it is said that the twelve Apostles began to understand the language of all nations, did they learn the grammar of all nations at that moment? No, they learned the language of the heart. The language of the heart speaks more loudly than words can speak. If the ears of the heart were open to hear that language, outer words would not be necessary.
