Now assurance goes far to set a child of God free. . . .It enables him to feel that the great business of life is a settled business, the great debt a paid debt, the great disease a healed disease, and the great work a finished work; and all other business, diseases, debts, and works, are then by comparison small. In this way assurance makes him patient in tribulation, calm under bereavements, unmoved in sorrow, not afraid of evil tidings; in every condition content, for it gives him a FIXEDNESS of heart.
It sweetens his bitter cups, it lessens the burden of his crosses, it smoothes the rough places over which he travels, and it lightens the valley of the shadow of death. It makes him always feel that he has something solid beneath his feet, and something firm under his hands—a sure friend by the way, and a sure home at the end. . .
There is a beautiful expression in the Prayer-book service for the Visitation of the Sick: “The Almighty Lord, who is a most strong tower to all them that put their trust in Him, be now and evermore thy defence, and make thee know and feel that there is none other name under heaven, through whom thou mayest receive health and salvation, but only the name of our Lord Jesus Christ.
