If we get attached to computers and other machines, we get far more attached to the traditional ways in which we have organized and run our lives. And though we all know that things could be better, we all hope that we can simply add the better bit on to the way we do things at the moment, so that we won't have to change too much, if at all. This is a challenge every generation has to face, but for Jesus and his contemporaries it was massive. They had lived for many centuries with a traditional way of life. They assumed, naturally enough, that if and when their God came back to rescue them he would support and vindicate that way. And Jesus was telling them that something new was happening. God was indeed doing what he'd always said, but the old machines they had been working with — the things they'd expected to happen — simply weren't adequate for this new moment.
In particular, he was replacing an overall mood of sadness and longing with an overall mood of celebration and hope. They used to fast regularly, to remember the times long ago when their nation had suffered awful disasters. Jesus was coming to do something that would always be remembered with celebration — so fasting wasn't appropriate! That was revolutionary. But it was appropriate.
We today fast during Lent, to remind ourselves of the sorrow and sin that still abounds in the world and in our own lives. But we do so as a people whose basic mode of life is celebration. God has brought the new world into being in and through Jesus. Don't try to put the new cloth on the old coat, or the new wine into old bottles. God is making everything new, and he's inviting us to the party.
