Jesus' Parables:

The Tower Builder

Luke 14: 28-30
For which of you, desiring to build a tower, doth not first sit down and count the cost, whether he have wherewith to complete it? 14:29 Lest haply, when he hath laid a foundation, and is not able to finish, all that behold begin to mock him, 14:30 saying, This man began to build, and was not able to finish.
