When, while we are praying, no hesitation intervenes and breaks down the confidence of our petition by a sort of despair, but we feel that by pouring forth our prayer we have obtained what we are asking for, we have no doubt that our prayers have effectually reached God. For so far will one be heard and obtain an answer, as he believes that he is regarded by God, and that God can grant it. For this saying of our Lord cannot be retracted: “Whatsoever ye ask when ye pray, believe that you shall receive, and they shall come to you.”
