He spake to them about prayer. He had taught them many lessons upon this all-important subject as they had been together. This solemn hour he seizes to perfect his teaching. They must be made to realize that they have an illimitable and exhaustless storehouse of good in God and that they can draw on Him at all times and for all things without stint, as Paul said in after years to the Philippians, "My God shall supply all your need according to His riches in glory by Christ Jesus."
