In other words, if we persevere in unceasing prayer and the other virtues, there will come upon us a mighty force, infinitely stronger than any we can exert. This force cannot be described in human language: in its great strength it overcomes our worst faults of character and the malice of the demons, conquering both the sinful inclinations of our soul and the disordered impulses of our body. 'There came a sound from heaven as of a rushing violent wind' (Acts 2:2); and this force from heaven drives out the evil that is always forcing us into sin.
