He told them another parable, saying: “The kingdom of heaven is like a mustard seed, which a man took and sowed in his field.
In this parable Jesus compares the kingdom of God to a mustard seed, emphasizing its initial smallness. The mustard seed was known as one of the smallest seeds, and the point here is that the kingdom of God in the world or in a person’s heart begins in an insignificant way. “The man” symbolizes Christ or any believer who sows the word of God. “The field” can be understood as this world or the individual heart where the word of God penetrates. This verse says that the kingdom of God begins to work at the moment it is received by faith, even when there is no visible result.
