In the gospel of Luke Chapter 14, verses 28-30, he admonishes us: "For which of
you, intending to build a tower, sits not down first and counts the cost,
whether he have sufficient to finish it? Lest haply, after he has laid the
foundation, and is not able to finish it, all that behold it begin to mock him,
Saying, This man began to build, and was not able to finish."
