Fifteenth Day
The apostles persevered in prayer in the holy cenacle. They had learned the necessity of prayer from Our Lord Himself. He inculcated it by command and example, and now they put His precepts into execution; they made prayer the chief preparation for the coming of the Holy Ghost. God was present among them, and heard them, for they were assembled in the name of Jesus. These long hours of supplication penetrated heaven and filled the earth with consolation; bringing upon them the graces and benedictions of Jesus. They had time to enter into themselves, and to cure their souls of the weakness of human nature. They had much cause for anxiety. What a battle, and apparently what a hopeless battle, was before them! They were to preach to the world; to conquer and to teach it the maxims of the Christian religion. They knew that the world was not willing to receive the Gospel, and yet they had to observe the injunction of Our Lord, to teach all nations, and to command them to observe all that Christ had taught. The apostles were filled with a great love for the salvation of mankind, and in the cenacle they began to be apostles of prayer, by which they were to be victorious over all difficulties.
Prayer.
Come, Holy Ghost, fill the hearts of Thy faithful, etc., etc.
