But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.
Professor Drummond tells of an over-laden coal barge which stood in the river: "A sailor reported to the captain that the water was gaining upon the vessel. The captain drove him away with scoffs. Twice, thrice, the warning was repeated. Each time the warning voice was unheeded. At last the barge began to give evidence of sinking. The captain ordered the men to the boats. They took their places. He then said: 'I told you there was plenty of time.' Then he took out his knife to cut the cable which bound the boat to the barge. He fell back with a cry of horror. The cable was an iron chain!" The eleventh hour is an hour of haste and danger and disappointment. The thread becomes a cord, the cord a cable, the cable a chain. The time to get clear of a sinking craft is now.
