Leaven

Another parable spake [Jesus] unto them; “The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till it was all leavened (Matthew 13:33).

When we seek to think about pleasant things, or to find ways of describing people or things positively, fungi rarely make the list of possible comparisons. They are normally something we do not often consider (like yeast, or perhaps mushrooms) or rather unpleasant things (like mold and fungal infections).

Yeast, or leaven, is known for its expansive properties– it multiplies very quickly. A small amount of yeast, in the right conditions, will quickly expand and fill the space it is provided. This has been the secret to bread making for generations– if you want a lump of dough to rise, it must have the right amount of yeast in it. As it bakes, the yeast multiplies and expands, and the entire lump rises. The yeast is also partly responsible for that addictive smell of baking bread!

The image of leaven as an agent that starts small but expands mightily is used a few times in Scripture. Sometimes it is used negatively– Jesus describes the teachings of the Pharisees and Sadducees as leaven (Matthew 16:6-12), and Paul warns that false teachings and sinful practices “leaven the whole lump” (1 Corinthians 5:6, Galatians 5:9).

But the image need not always be negative, for Jesus uses the image in a positive way in Matthew 13:33. Having described the Kingdom of Heaven as a mustard plant, with a small seed that grows to become a tree in which birds can nest (Matthew 13:31-32), Jesus continues down the same theme by describing the Kingdom as the leaven that a woman hid in three measures of flour that leavens the whole lump.

The general message of both parables are the same: the growth of the Kingdom will be exponential despite its humble origins. Just as a very little amount of yeast filled three measures of flour, so the Kingdom that begins with the Father, Son, and the Holy Spirit will expand from 12 to 3000+ to thousands upon thousands all over the earth (Acts 1:8, 2:41, etc.). The proclamation and advancement of the Kingdom is a wonderful story, clearly demonstrating the power and wisdom of God that is greater than anything man can imagine (cf. 1 Corinthians 1:18-25). If we wanted to get the most important message of life across, sending twelve fairly unreliable and uneducated witnesses would probably not make our list of possible options. Nevertheless, we see how effectively it was done by the power of God!

Nevertheless, there is a bit of distinction between the two parables. A mustard plant, by virtue of necessity, grows out in the open– while there are roots growing underneath the soil, without sun and water, the plant will not prosper. Yeast, however, works entirely behind the scenes. From the outside you can see the effect of the growth of the yeast– the rising lump of dough– but you cannot see how it is working internally.

So it is with the Kingdom. There are times when the growth of the Kingdom happens in a public and spectacular way, like on the day of Pentecost in Acts 2. Nevertheless, both in the first century and now, much of the advancement of the Kingdom happens more behind the scenes.

This growth comes about on the basis of many opportunities. It happens when believers go about doing good and living holy and upright lives (Romans 12:9, Galatians 2:10, 6:10). It happens as believers have conversations with friends, associates, relatives, and others about God’s truth in Jesus Christ (Romans 1:16, Colossians 4:5-6, 1 Peter 3:15). It happens as believers trust in and pray to God, as His Word is studied, as believers strengthen and build one another up, and in many other kinds of opportunities (cf. Ephesians 3:20-21, 1 Thessalonians 5:17-18, 2 Timothy 2:15, Hebrews 10:24-25).

We may not always see how this growth happens, but the results will be evident. God is magnified and praised while more and more come to the knowledge of the truth. This is how God expects the Kingdom to grow!

As we seek to serve our Lord and Savior Jesus Christ and advance His Kingdom, let us remember the humble leaven. No matter what public proclamation is made, let us remember that much of the way that God’s purposes are advanced are done behind the scenes, imperceptible to most. Let us trust in God and participate in His work of advancing His purposes on earth!
