Light in the darkness, sailor, day is at hand. Safety. This hymn, “The Life-Boat," has attained to great popularity. The incident upon which it is based, that of the rescue of a ship's crew by a life-boat, is given in detail by Mr. Sankey in his Sacred Songs, &c, No. 99 (large ed.). It is sometimes known by its refrain, "Pull for the shore," &c.
