The word, the seed sown by the sower, contains within itself the germ of the Kingdom of Heaven. Falling into our hearts, it begins to sprout into an ear of new life. But in this parable the sower does not act alone. Without soil—that is, without us—the seed cannot sprout. As Jesus observes, the more we participate in this process, the more fruit we bear. This produces an apparent injustice: the richer we are, the richer we become. Yet the issue here is probably not spiritual wealth, but how much of our capital—our time, attention, strength, and finally our whole life—we are willing to invest in this shared process of cultivating the Kingdom.

Jesus' parables are something halfway between amusing stories from everyday life and riddles: in them He explains the inexpressible, the Message of His Kingdom, in simple human language. Many of them begin just this way: "The Kingdom of God is like someone who..." - and then He sketches a situation familiar to His listeners, revealing to them the essence of His Gospel.

So, the most famous parable is about how the Word of God, like a seed, must fall into fertile soil in order to bear fruit and not be lost in vain. The evangelist wonderfully completes the parable by giving, immediately after it, the account of Jesus' family, where He speaks to the disciples a new riddle that expresses the same Message in other words: "Whoever hears the Word and does it has entered My family".

The listeners only have to compare these parable-riddles to understand what the Kingdom consists in that their Teacher brought to earth. Through his book, the evangelist offers this task not just to the small circle of disciples, but to all readers of the Gospel.

More precisely, "even what he thinks he has." Jesus by no means has in mind something like the saying "money goes to money." He is speaking of relations with God to which we are not accustomed: relations of trust and respect (in the end, of love). God offers His relationship to everyone, but He forces it on no one. A person who freely accepts this gift enters an unending process of developing this relationship, whose goal is the deification of the person, the fullness of that person's entry into the life of God. But a person who thinks that everything is fine with him, that the relationship with God he thinks he has is enough for him, by that very fact closes himself off from God and does not accept from Him what God gives; and that means he breaks even the weak threads that had still kept him afloat in this life. "Take care, then, how you hear"; tune your "receivers" to the wavelength of God's grace.
