So, therefore, whoever of you does not renounce all that he has cannot be my disciple. Luke 14:33
“Discipleship means saying a final ‘good-bye’ to one’s possessions. Just as one cannot attempt a venture without having sufficient resources to complete it, but will need to put everything into it in order to be successful, so the disciple must be continually ready (present tense) to give up all that he’s got in order to follow Jesus.”
