4 Witnesses, then, as we are of all these great benefits which God has granted through the benign influence of the Virgin in those fifty years now about to be completed, why should we not believe that our salvation is nearer than we thought; all the more since we know from experience that, in the dispensation of Divine Providence, when evils reach their limit, deliverance is not far distant. "Her time is near at hand, and her days shall not be prolonged. For the Lord will have mercy on Jacob and will choose one out of Israel" ( Isaias xiv., 1). Wherefore the hope we cherish is not a vain one, that we, too, may before long repeat: "The Lord hath broken the staff of the wicked, the rod of the rulers. The whole earth is quiet and still, it is glad and hath rejoiced" ( Ibid . 5, 7).
