Now large crowds were traveling with him; and he turned and said to them, “Whoever comes to me and does not hate father and mother, wife and children, brothers and sisters, yes, and even life itself, cannot be my disciple…. So therefore, none of you can become my disciple if you do not give up all your possessions.
Luke 14:25‭-‬26‭, ‬33 NRSV

So Jesus is walking and crowds are following him to hear what he has to say and I suspect hoping to see a miracle or two.

A disciple is a follower, one who walks behind or sits at the feet of the teacher. Why the hyperbole? I wonder if the clue is in the crowds; were there those jostling to be at the front? Was this Jesus restating the parable of the dinner guests vying for top table place? This is where the story appears in the gospel of Luke so that is possibly true… you may be elbowing others to be at the front, but being my disciple carries a cost.

What about verse 33? Ouch!
