When the gospel of the coming Kingdom of God is preached in all the world as a witness (Matthew 24:14), the ears that hear it are not always receptive of this priceless knowledge. In the Parable of the Sower (Matthew 13:3-8, 19-23; Mark 4:3-9, 14-26; Luke 8:4-8, 11-15), Jesus reveals why, using three component elements: the sower, the seed, and the soils.
This parable describes what happens after the seed is sown, the different types of soils on which it falls, and the resultant effects. The parable's focus is not on the sower as much as on the various soils. Nevertheless, the sower—Jesus Christ (Matthew 13:37)—is not incidental, for without Him there could be no sowing and thus no possibility of fruit being produced.
