In my last post, we saw Jesus teaching the crowd through parables. He talked about the kingdom of God being like a mustard tree. It’s a tree that once it starts growing, it will be impossible to remove.

Now the Lord gives another illustration of the kingdom.

Again he asked, “What shall I compare the kingdom of God to? It is like yeast that a woman took and mixed into a large amount of flour until it worked all through the dough.”

Luke 13:20-21 NIV

Here we see that the kingdom of God is like yeast. It was used in making bread.

Personally, I love making my own bread. There’s nothing like the smell of fresh bread while it’s baking. Then, putting butter on it while it’s still hot from the oven. It’s wonderful!

This verse, however, talks about it in a way that’s well beyond my capabilities. According to the words that Jesus used, this woman put yeast into about a half bushel of flour. I’ve never made that much bread at one time.

There are some things that we need to understand if we want to learn from this parable. First of all, yeast is a living organism. Even though it appears dry and lifeless, as soon as it comes into contact with water, it springs to life.

At that point it begins to grow and multiply. As it grows, it consumes sugars and produces carbon dioxide gas. That’s the tiny bubbles that cause the bread to rise. Without yeast, you just get crackers.

This is important because the church is a living organism. We’re the body of Christ on earth. We’re not just some sort of social organization. Because of this, the whole is greater than just the sum of its parts.

But there’s another important aspect of yeast. Once incorporated into the dough, it vanishes. There’s absolutely no way to remove it, once you add it into the flour. Just like the mustard tree, once it starts, there’s no stopping it.

The thing about yeast is that it does its work in secret. You can’t see how it works, but the dough begins to change. It starts to grow and take on that delicious fluffy texture.

We might think that the church operating outside of society. After all, we’re in the world, but not of the world. Although it’s true that we’re not the flour – the world is the flour – we should be having an effect on all those around us.

I know that a lot of the Scripture talks about yeast as if it’s a bad thing. At Passover, the Jews were to clean all of the yeast out of their homes. Then they were only to eat bread made without yeast; those were the matzoh crackers.

However, that’s not the whole story. The next feast after Passover was Pentecost. It happened fifty days after Passover. It was on this feast that the Holy Spirit came upon the church in power (Acts, chapter 2).

Look at God’s command for celebrating the feast of Pentecost.

From wherever you live, bring two loaves made of two-tenths of an ephah of fine flour, baked with yeast, as a wave offering of firstfruits to the Lord.

Leviticus 23:17 NIV

Pentecost was celebrated with a yeast bread. In the New Testament, the day of Pentecost was when the church was commissioned to be a witness to the world. You could say that that was the day the yeast was put into the flour and watered by the Holy Spirit.

Now the dough is rising. There’s nothing that can be done to stop the process. Our goal should be to have that positive effect on the world around us.

As we spend time with the Holy Spirit, He can activate us to be what we’re called to be. We will then see the power of God at work in our homes, schools, workplaces, and social environments. That’s who we’re meant to be as the body of Christ.

Question: What kind of effect are you having on those around you?
