I remember when Dr. Arnott, who has gone to God, was delivering a sermon, he used this illustration. The sermon and text have all gone, but that illustration is fresh upon my mind to-night and brings home the truth. He said: "You have been sometimes out at dinner with a friend, and you have seen the faithful household dog standing watching every mouthful his master takes. All the crumbs that fall on the floor he picks up, and seems eager for them, but when his master takes a plate of beef and puts it on the floor and says, 'Rover, here's something for you,' he comes up and smells of it, looks at his master, and goes away to a corner of the room. He was willing to eat the crumbs, but he wouldn't touch the roast beef -- thought it was too good for him." That is the way with a good many Christians. They are willing to eat the crumbs, but not willing to take all God wants. Come boldly to the throne of grace and get the help we need; there is an abundance for every man, woman and child in the assemblage.
