Whoever does not bear his own cross and come after Me cannot be My disciple.
… 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.”
Luke 14:27-30 (ESV)
