Luke 14:28-30, 33

For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it? Otherwise, when he has laid a foundation and is not able to finish, all who see it begin to mock him, saying, ‘This man began to build and was not able to finish.’

So therefore, any one of you who does not renounce all that he has cannot be my disciple.
