Luke 14:28-32

14:28 For which of you, wanting to build a tower, doesn’t sit down first and compute the cost to see if he has enough money to complete it? 14:29 Otherwise, when he has laid a foundation and is not able to finish the tower, all who see it will begin to make fun of him. 14:30 They will say, ‘This man began to build and was not able to finish!’ 14:31 Or what king, going out to confront another king in battle, will not sit down first and determine whether he is able with ten thousand to oppose the one coming against him with twenty thousand? 14:32 If he cannot succeed, he will send a representative while the other is still a long way off and ask for terms of peace.
