The efficiency of a thing is in direct proportion to its nature. Every cause produces its full effect, as water rises to its proper level. A great design must have a great purpose to accomplish. In our solar system the sun is the greatest body and the greatest force; and it becomes the source of all the energies of its attendant planets. The Holy Eucharist is the greatest and most powerful of institutions on this earth. It is not a mere creature, it is the Son of God Himself. It is not an instrument or channel of divine operations, it is the original source of all grace and spiritual life. Jesus Christ is there, not in mere figure, not as dead and passive, but in His living body actuated by His soul and Divinity; He is there with all His divine power and infinite love; He is there to act upon us and upon the whole world. The Blessed Sacrament is the sun of the spiritual world, the source of all light, heat, motion, energy, life. It works steadily, silently, imperceptibly, but universally and irresistibly. Consider the activity of the great powers of nature; consider the activity of the combined intelligence of humanity; consider the power and the work of Our Lord during His earthly course. Much greater than all this is the efficiency of Our Lord continuing the greatest of the divine works from His retreat in the tabernacles of our churches. The Blessed Sacrament is like the Ark in the house of Obededom, a center of all blessings. The Victim raised up from the earth daily in the Mass is doing all that is consistent with human liberty to draw all souls unto Himself. Look to the Blessed Sacrament as the source of all your strength and life; have recourse to it in all your needs.
