Luke 14:28-33

28 For which of you, intending to build a tower, does not sit down first and count the cost, whether he has enough to finish it--

29 lest, after he has laid the foundation, and is not able to finish, all who see it begin to mock him,

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

31 Or what king, going to make war against another king, does not sit down first and consider whether he is able with ten thousand to meet him who comes against him with twenty thousand?

32 Or else, while the other is still a great way off, he sends a delegation and asks conditions of peace.

33 So likewise, whoever of you does not forsake all that he has cannot be My disciple.
