Luke 14:29

27 And whosoever doth not bear his cross, and come after me, cannot be my disciple.

28 For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it?

Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold 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, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand?

Do read the surrounding verses too, because the context often says more than a single verse.
