Luke 14:28-30

14:28 For which of you, wanting to build a tower, doesn’t sit down first and compute the cost to see if he has enough money to complete it? 14:29 Otherwise, when he has laid a foundation and is not able to finish the tower, all who see it will begin to make fun of him. 14:30 They will say, ‘This man began to build and was not able to finish!’
