“The Saviour knew that no argument, however logical, would melt hard hearts or break through the crust of worldliness and selfishness. He knew that His disciples must receive the heavenly endowment; that the gospel would be effective only as it was proclaimed by hearts made warm and lips made eloquent by a living knowledge of Him who is the way, the truth, and the life.”
