How much will we take?

I have just been thinking this issue through on another blog that I write for young people, but also think that it is an important one for us as youth workers. How much are we prepared to put up with from our young people? When they start being awkward, not listening, not following guidence, going there own way, causing disruption, how much will we put up with? the reason why I started thinking of this was due to how much Jesus put up with. He chose 12 "friends", some argued about having the best seat in Heaven,One stole money and betrayed him, another even denied knwoing him, but yet Jesu still washed their feet, had communion with them as well. Even wth Judas who was about to betray him a couple of hours later. So if Jesus demonstrated so much by his actions, and put up with so much, what does this tell us as youth workers?
