Won’t you first sit down and estimate the cost to see if you have enough money to complete it? 29 For if you lay the foundation and are not able to finish it, everyone who sees it will ridicule you, 30 saying, ‘This person began to build and wasn’t able to finish.’ 31 “Or suppose a king is about to go to war against another king. Won’t he first sit down and consider whether he is able with ten thousand men to oppose the one coming against him with twenty thousand? 32 If he is not able, he will send a delegation while the other is still a long way off and will ask for terms of peace. 33 In the same way, those of you who do not give up everything you have cannot be my disciples. 34 “Salt is good, but if it loses its saltiness, how can it be made salty again? 35 It is fit neither for the soil nor for the manure pile; it is thrown out. “Whoever has ears to hear, let them hear.”
