Season 10 - Week 1

“Out with the old”

Jesus once said, “The kingdom of heaven is like leaven that a woman took and mixed in with three measures of flour until all of it was leavened” (Matt. 13:33). My youth group contemplated this while we mixed together some warm water, sugar, and yeast. It didn’t take long for the yeast to form a large mound of bubbles and let off the smell of fermenting sugar.

Bread-making is a familiar process for our young people. I’m a pastor and youth leader in a small rural church in Upstate New York, where most of our young people’s families raise poultry, cultivate vegetables, and often make their own bread. They knew what Jesus was trying to say here. All you need is a little bit of yeast - just 1 to 2 teaspoons - and you can get multiple loaves of bread to rise. Likewise, the natural process of the kingdom of heaven is growth. As we looked at this passage, we talked about how God wants growth for our lives, both in the size of our group (evangelism) and in the quality and depth of our faith (discipleship). This was an easy parable for our youth group to understand. It’s no wonder that just a few verses later in Matthew 13, we read that Jesus taught in parables to reveal life’s hidden mysteries. Jesus was creative in his teaching to make the Gospel clear and relevant.

But that wasn’t the only time Jesus used yeast figuratively. He also said, “Watch out, and beware of the yeast of the Pharisees and Sadducees” (Matt. 16:6). This saying is not quite as easy to understand. What makes some yeast good and some yeast bad? Understanding this saying is actually quite important for understanding why Jesus spoke in parables and why our own language about God should evolve and remain creative.

Jesus and his Jewish audience understood something that eludes many modern Christians: the Passover prescriptions of Exodus 12. Every year, Jews would throw out their old yeast and start with fresh yeast. Additionally, the barley harvest occurred shortly after Passover, which provided an opportunity to start a new leavened lump of dough made from flour from the new harvest God had provided. This did two things. First, it removed unsanitary dough that could cause harm. In addition to collecting yeast fungus, a leavened dough lump could also collect other bacteria that wasn’t safe to eat. Second, it acknowledged that God was presently doing something among the people by providing a new harvest. The “yeast” of the Pharisees that Jesus warned his disciples about was traditionalism: holding on to the old ways for the sake of the old ways.

In other words, the Pharisees hadn’t updated the conversation about God, and it was having detrimental effects.

Here’s what it means when we tie these two passages together: Our ministry with young people should introduce them to a living and dynamic faith that flows out of our own relationships with Christ and seeks to grow in them. The faith that we model and that we nurture in our young people should also incorporate regular self-evaluation. Without refreshing our faith and staying aware of what God is doing in the present moment, the very same faith that was once dynamic and growing can become dangerously harmful to us and the people we share it with, just like old leaven that hasn’t been replaced.

For my young people, this might mean not just understanding their faith in terms of the parables that make sense in their rural context, but also refreshing their conversation by learning what faith can look like in an urban context, or in a more multicultural context, or in a foreign context. Faith can be enlightened through many different and creative ways of thinking. Faith can make sense anywhere.

Season 10 Episode 1

Matthew 16:5-12

'When they went across the lake, the disciples forgot to take bread. "Be careful," Jesus said to them. "Be on your guard against the yeast of the Pharisees and Sadducees."

They discussed this among themselves and said, "It is because we didn’t bring any bread."

Aware of their discussion, Jesus asked, "You of little faith, why are you talking among yourselves about having no bread? Do you still not understand? Don’t you remember the five loaves for the five thousand, and how many basketfuls you gathered? Or the seven loaves for the four thousand, and how many basketfuls you gathered? How is it you don’t understand that I was not talking to you about bread? But be on your guard against the yeast of the Pharisees and Sadducees." Then they understood that he was not telling them to guard against the yeast used in bread, but against the teaching of the Pharisees and Sadducees.'

Questions & Challenges


What images that Jesus used make most sense to you?

Jesus drew on the imagery of the world around him, and some of that translates to our context and some doesn't. Whichs of Jesus' parables and images makes most sense to you? Maybe you have a personal favourite. Are there some that feel close to your experience or context? And which ones feel the most baffling or empty?


Out with the old...

What might it mean to reimagine the language we use to talk about the kingdom of God? Can you think of some modern translations for Jesus' ancient metaphors? Could you find a way of communicating with others this week - it might be in a conversation, or in a youth group setting - something about Jesus, through metaphors and pictures from our world? How can we talk about God using the things we are familiar with from our every day life - God is like (or not like) a mobile phone, snapchat, contactless payment...
