Jesus also used this illustration: “The Kingdom of Heaven is like the yeast a woman used in making bread. Even though she put only a little yeast in three measures of flour, it permeated every part of the dough.” [Matthew 13:33 (NLT)]
Immediately after the Parable of the Mustard Seed, Jesus compared the Kingdom of Heaven to the yeast a woman added to “three measures of flour” when making bread. While “measures” seems vague, the original word used wasn’t. It was seah (about a peck and a half of flour) and three seahs were over 167 cups (nearly 50 pounds) of flour. This was an enormous amount of flour for just “a little yeast” and, as He did in the previous parable, Jesus used hyperbole to emphasize the power of something very small. The question in this parable is whether the yeast is a metaphor for a bad or a good thing.
This is the first mention of leavening in the New Testament but, by the 1st century, yeast had come to represent sin. Sticking to yeast’s traditional symbolism, some commentators liken the story’s yeast to false doctrine that can sneak into the Kingdom and see this parable as a warning about the dangerous power of false teaching in the Church. Enekrupsen is the Greek word used to describe the woman’s action in adding the yeast and this is its only use in Scripture. From egkruptó, which literally meant to bury within, enekrupsen has been translated with different meanings. Some translate it as hid or concealed (which implies she did something sneaky and devious in adding yeast) while others merely translate it as put, blended, or mixed in. Since enekrupsen is used both ways in other Greek literature, we can’t be sure which correctly communicates Jesus’ meaning. Considering that bread was being made, it seems that burying yeast in the dough would be expected rather than sneaky.
I find it hard to interpret this parable in a way that associates anything sinful or evil with the Kingdom of Heaven. Although His listeners may have expected yeast’s power to represent something bad, Jesus’ parables rarely fit his listeners’ expectations. When they anticipated one thing, He usually gave them another! That a Levite and priest had failed their fellow Jew while a hated Samaritan was the hero of one parable was as surprising as a beggar ending up in Abraham’s bosom at a heavenly banquet when the rich man ended up tormented in Hades. Jesus threw society’s expectations out the window when telling of a father who’d been offended and hurt by his wastrel son. Upon the boy’s return, rather than rejecting him as the law required, the father ran to welcome him home, restored him to the family, and even had a festive celebration in the boy’s honor. Equally unexpected was the story of vineyard workers getting the same pay regardless of how long they worked and the prayers of a tax collector being heard when the Pharisee’s were not.
I agree with the commentators who take this parable at face value. Believing Jesus simply is speaking of the pervasiveness and power of yeast, they see this analogy as a continuation of the lesson in the mustard seed parable. Rather than a corrupting influence, the leaven, like the mustard seed, illustrates that great things can come from small beginnings. Yeast is even smaller than the tiny mustard seed and yet both are powerful enough to expand and effect change. While both parables illustrate the extensive growth of the Kingdom, the second parable emphasizes the Kingdom’s transformative power. Just as yeast changes dough, the Kingdom will transform the world! In both parables, the message is clear—the Messianic Kingdom comes from small beginnings, operates quietly, but has the power to accomplish great things! That God’s Kingdom would start from small and humble beginnings to grow and change a much larger entity (the world) would have been reassuring news to Jesus’ small band of disciples.
Like the Kingdom of Heaven, yeast is a living organism. Like the Holy Spirit, yeast is invisible once in the dough and yet its effect, like that of the Spirit, becomes obvious as it permeates the mixture. Just as leavened dough grows from inside out, the Kingdom moves from our hearts into our actions and from our actions into the world. Yeast transforms what it mixes with and, as we are transformed, we transform those with whom we interact. Just as yeast needs certain conditions to grow, so does the Kingdom and, just as there are 1,500 different kinds of yeast, God’s Kingdom is made up of a wide assortment of people. Yeast is found everywhere—from the bottom of the ocean to the Arctic and from flower nectar to the lining of our stomachs—and God’s Kingdom should be as pervasive! Indeed, the Kingdom of Heaven is alive, it’s everywhere, it takes attention and patience to grow, and it transforms all it touches.
What Jesus’ listeners probably didn’t understand was that the Kingdom already had arrived. But, like a tiny mustard seed, a bit of yeast, or a baby in a manger, it entered the world quietly without fanfare. Like a small yellow flower, a lump of dough, or an itinerant rabbi from Nazareth, the Kingdom didn’t look that impressive at first. Appearances, however, can be misleading. Like a mustard seed that grows 1,440 times its original size or the more than fifty loaves of bread leavened by that bit of yeast, the Kingdom will increase and prevail. In the end, when Christ returns as a conquering king, no one will be able to miss its arrival. Until then, like a small amount of yeast, God’s Kingdom will transform the hearts and lives of all it touches! May we always remember that little things become great when God is at work!
When the dough is leavened, then to the oven with it; trials and afflictions commonly attend this change; but thus saints are fitted to be bread for our Master’s table. [Matthew Henry]

Following the Parable of the Sower and the Soils, Jesus told another parable about the coming of the Kingdom. In the Parable of the Weeds, after the farmer plants wheat, his enemy sows weeds in the same field. Jesus’ hearers would have known the weed likely was darnel. Called wheat’s “evil twin,” it looks and behaves much like wheat. When wheat is consumed it gives life but, when darnel is consumed, this inedible look-alike causes nausea and even death. Sowing weeds in a field was an act of sabotage and Roman law specifically prohibited doing so with darnel. When nations went to war, agricultural vandalism was a common practice. Olive trees were cut down, grape vines destroyed, and fields were salted so nothing would grow.
Judas wasn’t the only one who betrayed Jesus that Thursday night. With his three denials, Peter also betrayed our Lord. Both men were filled with remorse but neither man could undo what had been done. One never lost faith and hung in there; the other lost faith and hung himself. One stayed around for the resurrection to see the living Christ and to experience Jesus’ forgiveness; the other missed his opportunity for redemption when he gave up all hope. One became the humble willing servant of the Lord and the rock of the church; the other one’s name lives on in ignominy and is synonymous with betrayal and treason.
The Amalekites were a warlike nomadic tribe who frequently raided settlements to carry off plundered goods. About six weeks into the Israelites’ exodus from Egypt, these marauders made an unprovoked attack on the weary refugees while they camped at Rephidim. Moses commissioned Joshua to lead an army against their enemies the following morning. Joshua’s army, however, wasn’t made up of soldiers! Facing the veteran warriors of Amalek were men who less than two months earlier had been enslaved brick makers and field laborers! Worse, this unseasoned army was led by a general as inexperienced as were they. Nevertheless, Israel’s men set out to battle while Moses, his brother Aaron, and a man named Hur (who Jewish tradition believes was married to Miriam and brother-in-law to Moses) climbed to the top of a nearby hill to watch. As Israel fought their powerful foes, Moses extended his arms and held out his staff for all to see.
As we came together in worship, each of us bringing the Lord our own private sins, sorrows, doubts, and fears, the hymn’s words, “Just as I am… I come, I come,” seemed a fitting way to start the service. Because its heartfelt words are so relatable, Just as I Am is one of my favorite hymns. Curious about its origin, I learned that its words were written by a Victorian hymn writer named Charlotte Elliott. The daughter of an evangelist, she suffered a serious illness at the age of 32 that left her an invalid for the rest of her life. Angry about what she perceived as uselessness because of her disability, Elliott became severely depressed and spiritually lost. After a visiting minister counseled her to come to Jesus, she asked how she could come to Him when all she had was her anger, sadness, questions, and broken body. The clergyman’s response was simple: “Come to Him just as you are.” Although she gave her life to Christ at that time, she continued to be plagued by depression.
