In Daniel 2, God taught us a general doctrine of the kingdom. The teaching was couched in terms of a prophesy, but it was still a teaching of doctrine.
The kingdom of Jesus Christ was represented by a rock. This rock would grow into a mountain and cover the whole earth. The teaching is that Christ’s kingdom would start small, then grow to cover the whole earth.
Jesus taught this same doctrine of the kingdom. He used 2 analogies, a mustard seed and yeast. These were common elements in first century Israel. Jesus used them so that people would understand. In Matthew 13:31, Jesus said the kingdom of heaven is like a grain of mustard seed. It is a small seed, but grows into the largest of garden plants, so big that birds may nest in it. Mustard plants in Israel grew to 6 feet tall. The point Jesus made is the kingdom starts very small, with a few disciples, but becomes very large in time.
The 2nd analogy was yeast or leaven. Bread was a staple of diet for the people of Jesus’ time, especially poor people. They added yeast to wheat or barley dough to make it rise and expand, just as we do today. I once made my wife’s recipe for bread to help out. I put a small packet of yeast in a bowl of warm water to “bloom”, then added it to the mixture for the dough. After covering it and letting it set, it rose to several times its original size. So, Jesus said, will his kingdom grow from a small start to a large finish. As the yeast permeated the dough, the gospel of the kingdom will permeate the entire world.
What does this mean for us? Here are a few things.
