Luke 13:18-19

After the people had asked a few questions, Jesus spoke another parable: “The kingdom of heaven is like a grain of mustard seed which a man sowed in his field. Now a mustard seed is the least of seeds, but when it is full grown, it becomes the greatest of all herbs and is like a tree so that the birds of heaven are able to come and rest in the branches thereof.”

“The kingdom of heaven is also like leaven which a woman took and hid in three measures of meal, and in this way it came about that all of the meal was leavened.”

The next day Jesus again taught the people from the boat, saying: “The kingdom of heaven is like a man who sowed good seed in his field; but while he slept, his enemy came and sowed weeds among the wheat and hastened away. And so when the young blades sprang up and later were about to bring forth fruit, there appeared also the weeds. Then the servants of this householder came and said to him: ‘Sir, did you not sow good seed in your field? Whence then come these weeds?’ And he replied to his servants, ‘An enemy has done this.’ The servants then asked their master, ‘Would you have us go out and pluck up these weeds?’ But he answered them and said: ‘No, lest while you are gathering them up, you uproot the wheat also. Rather let them both grow together until the time of the harvest, when I will say to the reapers, Gather up first the weeds and bind them in bundles to burn and then gather up the wheat to be stored in my barn.’”

Before he dismissed the group for the night, Jesus said: “Now will I tell you the last of the parable of the sower. I would test you to know how you will receive this: The kingdom of heaven is also like a man who cast good seed upon the earth; and while he slept by night and went about his business by day, the seed sprang up and grew, and although he knew not how it came about, the plant came to fruit. First there was the blade, then the ear, then the full grain in the ear. And then when the grain was ripe, he put forth the sickle, and the harvest was finished. He who has an ear to hear, let him hear.”

They looked upon the coming of the kingdom in the hearts of men as a gradual development, like the leaven in the dough or like the growing of the mustard seed. They believed that the coming of the kingdom in the racial or world sense would be both sudden and spectacular. Jesus never tired of telling them that the kingdom of heaven was their personal experience of realizing the higher qualities of spiritual living; that these realities of the spirit experience are progressively translated to new and higher levels of divine certainty and eternal grandeur.

“A sower went forth to sow, and it came to pass as he sowed that some seed fell by the wayside to be trodden underfoot and devoured by the birds of heaven. Other seed fell upon the rocky places where there was little earth, and immediately it sprang up because there was no depth to the soil, but as soon as the sun shone, it withered because it had no root whereby to secure moisture. Other seed fell among the thorns, and as the thorns grew up, it was choked so that it yielded no grain. Still other seed fell upon good ground and, growing, yielded, some thirtyfold, some sixtyfold, and some a hundredfold.” And when he had finished speaking this parable, he said to the multitude, “He who has ears to hear, let him hear.”

“The kingdom of heaven is also like a treasure hidden in a field, which a man discovered. In his joy he went forth to sell all he had that he might have the money to buy the field.”

“This new kingdom is like a seed growing in the good soil of a field. It does not attain full fruit quickly. There is an interval of time between the establishment of the kingdom in the soul of man and that hour when the kingdom ripens into the full fruit of everlasting righteousness and eternal salvation.

“The kingdom of heaven is also like a merchant seeking goodly pearls; and having found one pearl of great price, he went out and sold everything he possessed that he might be able to buy the extraordinary pearl.”

This gospel of the kingdom is a living truth. I have told you it is like the leaven in the dough, like the grain of mustard seed; and now I declare that it is like the seed of the living being, which, from generation to generation, while it remains the same living seed, unfailingly unfolds itself in new manifestations and grows acceptably in channels of new adaptation to the peculiar needs and conditions of each successive generation. The revelation I have made to you is a living revelation, and I desire that it shall bear appropriate fruits in each individual and in each generation in accordance with the laws of spiritual growth, increase, and adaptative development. From generation to generation this gospel must show increasing vitality and exhibit greater depth of spiritual power. It must not be permitted to become merely a sacred memory, a mere tradition about me and the times in which we now live.
