Luke 14:28-33
28“For which one of you, when he wants to build a tower, does not first sit down and calculate the cost to see if he has enough to complete it? 29“Lest, when he has laid a foundation and is not able to finish, all who observe it begin to ridicule him, 30saying, ‘This man began to build and was not able to finish.’ 31“Or what king, when he sets out to meet another king in battle, will not first sit down and aconsider whether he is strong enough with ten thousand men to encounter the one coming against him with twenty thousand? 32“Or else, while the other is still far away, he sends 1a delegation and asks for terms of peace. 33“So then, none of you can be My disciple who adoes not give up all his own possessions.
