Parable of the Mustard Seed
Over against the mighty numbers of the worshipers of heathen gods and even of the Jews who acknowledged the true God, those who proclaimed the kingdom were a tiny minority. Jesus teaches them not to be hypnotized by size. These tiny beginnings would grow into something greater by far than any of the religions found in the disciples’ contemporary world.
This points up the strong contrast between the tiny seed and the tree that is the end result of the seed. The kingdom may be considered insignificant in its beginnings and was doubtless despised by many in Jesus’ day because of this. But in the end its growth would be extensive; it would be a very great kingdom indeed. There
What may not look like much to the world will in fact fulfill all God’s promises.

If there is a difference between the two parables, it may be that the mustard seed portrays extensive growth and the yeast depicts intensive growth. No Jew would have made these comparisons. How could God’s kingdom be compared to the smallest of seeds? Jesus deliberately uses this shocking illustration to challenge how most Jews thought about the coming of God’s kingdom.
