To-day is the Sunday of expectation, and it brings to our minds that upper chamber in Jerusalem, where the little band of the chosen disciples of the Lord were gathered together waiting for the coming of the Holy Ghost. There were the eleven Apostles and the faithful women, and Mary, the Mother of Jesus, and his brethren. "All these," says the sacred chronicler, "were persevering with one mind in prayer." Hence the Epistle of to-day urges us to imitate them, and begins with the exhortation: "Dearly beloved, watch in prayers." We too must watch and wait for the coming of the Holy Ghost. He has, indeed, already come into our souls in Holy Baptism, cleansing them from original sin and making them his temples. He has come again in Confirmation, with all the fulness of his sevenfold gifts, to make us strong and perfect Christians and soldiers of Christ. Yet he comes to us continually every day, knocking at the door of our hearts and begging for admittance. Every impulse of what is known as actual grace is from the Holy Ghost, and such graces we are receiving all the time, every hour of the day. We must therefore prepare ourselves for his coming, and when he has entered into our souls we must strive to keep him there. The Holy Ghost is the life of our souls. It is his constant presence and indwelling which is the state of grace which makes us pleasing to God. To obtain and to preserve this abiding presence of the Holy Ghost we must imitate the Apostles in their watchfulness and prayer. We must watch lest the time of temptation should find us unprepared and off our guard; we must pray that the Holy Ghost may come into our hearts, bringing with him ever richer treasures of divine grace; that he may take possession of our souls and make them all his own; that he may guide our minds, and with the fire of his love inflame our hearts to do his holy will in all things. {265} But we must first of all prepare for the Holy Ghost by cleansing our souls from sin. Where sin reigns the Holy Ghost can never dwell. The Apostles prepared for his corning by penance. To that upper chamber in Jerusalem came St. Peter, who had denied his Lord, St. Thomas, who had doubted his resurrection, and the others who had wavered in their faith, and, in the time of trial, had forsaken their Master and fled. But now they had been convinced of their error, and they came together with sorrow for their past unfaithfulness, and a full determination to lay down their lives, if need be, for him who had died for them. This is the spirit in which we should prepare for the Holy Ghost. If your hearts are defiled with mortal sin, delay not the time of penance. The Holy Ghost is ready to descend upon you. He only waits for you to do your part. Make ready, then, a place in your heart, that he may enter in and dwell there.
