Luke 14:28-30
Luke 14:28-30 NCV
If you want to build a tower, you first sit down and decide how much it will cost, to see if you have enough money to finish the job. If you don’t, you might lay the foundation, but you would not be able to finish. Then all who would see it would make fun of you, saying, ‘This person began to build but was not able to finish.’
