Luke 14:28-33

28For which of you, desiring to build a tower, doth not first sit down and count the cost, whether he have wherewith to complete it? 29Lest haply, when he hath laid a foundation, and is not able to finish, all that behold begin to mock him, 30saying, This man began to build, and was not able to finish. 31Or what king, as he goeth to encounter another king in war, will not sit down first and take counsel whether he is able with ten thousand to meet him that cometh against him with twenty thousand? 32Or else, while the other is yet a great way off, he sendeth an ambassage, and asketh conditions of peace. 33So therefore whosoever he be of you that renounceth not all that he hath, he cannot be my disciple.
