Luke 14:28-33

28For which of you, desirous of building a tower, does not first sit down and count the cost, if he have what [is needed] to complete it;

29in order that, having laid the foundation of it, and not being able to finish it, all who see it do not begin to mock at him,

30saying, This man began to build and was not able to finish?

31Or what king, going on his way to engage in war with another king, does not, sitting down first, take counsel whether he is able with ten thousand to meet him coming against him with twenty thousand?

32and if not, while he is yet far off, having sent an embassy, he asks for terms of peace.

33Thus then every one of you who forsakes not all that is his own cannot be my disciple.
