<p>14:28<i> For which of you, desiring to build a tower, does not first sit down and count the cost, whether he have enough to complete it?</i>-Virtually nobody in the audience had ever planned to build a tower (Gk. 'castle'). So the Lord means 'If you were mega wealthy and had money to build a tower, wouldn't you even then be careful to understand the total cost in advance, lest even your wealth is all taken away by it?'. They were asked to imagine they were wealthy. The Lord was seeking to elevate their minds upwards to consider the great potential which they had. But all the same, they must count the cost; and realize that to build a castle / tower was beyond them. This is the implication of :31 and :33. Capitulation is required. Or it could be that the Lord is asking them as poor people to seriously calculate how much it would cost to build a tower / castle, and realize it was beyond them. Recognizing our spiritual bankruptcy, our inability to pay, and throwing ourselves upon the Lord- this is the same as forsaking all we have (:33).</p>
