Luke 14:28 read with the dictionary and then joined to Habakkuk. Which of you desiring to build a tower does not first sit down and count the cost, whether you have enough to complete it? The coin is not dollars and cents - the cost is persistency, vigilance, faithfulness and courage, and the question is whether you have those virtues in sufficient quantity to hold an assumption against tomorrow's denial. Then the word: the word translated tower means a simple watch-tower, which sends him to Habakkuk 2 - and now I will stand, and watch, and take my station upon the tower, and I will look forth to see what he will say unto me; write the vision, make it plain upon tablets that he may run who reads it; for the vision has its own appointed hour, it ripens, it will flower, if it be long then wait, for it is sure and it will not be late. So the tower being built is the watching itself, and the cost is what it takes to keep watching. Neville makes the counting explicit as a list of questions to put to yourself before you start: have I the persistency, the faithfulness, the courage, and am I willing to start with what I have in the hope that it really is enough to build the tower? He defines faithfulness on the spot as loyalty to this unseen reality. About five lectures carry the watchtower; 1021 carries the counting.
