This coming Sunday is the 15th Sunday in Ordinary Time. In the context of Jesus’ ministry the parable serves to explain why it is that the good news of the kingdom meets with such a varied response as we have seen in chapters 11–12, from enthusiastic acceptance to outright rejection. The fault lies not in the message, but in those who receive it.
People are both inadequate in themselves to respond as the word of the kingdom requires (compacted and shallow soil), and also exposed to competing pressures from outside (tribulation and persecution, anxieties and lures, and behind them all the evil one himself). The wonder is not that some do not produce fruit, but that any do. But here lies the parable’s encouragement both to Jesus’ followers then and to all who since then have preached this same gospel; not all will respond, but there will be some who do, and the harvest will be rich.

Mark alone records this parable: He said, “This is how it is with the kingdom of God; it is as if a man were to scatter seed on the land and would sleep and rise night and day and the seed would sprout and grow, he knows not how. Of its own accord the land yields fruit, first the blade, then the ear, then the full grain in the ear. And when the grain is ripe, he wields the sickle at once, for the harvest has come.” (Mark 4:26-29)
