The Lord scatters the seed of the word of God freely and with abundance but knowing that it may fall on poor soil, which will not allow a seed to mature because of dryness, or that its vital force may be extinguished, choked by thorn bushes. Yet the sower does not lose heart, for he knows that part of this seed is destined to find "good soil", namely, ardent hearts capable of receiving the word with willingness to help it mature through perseverance and yield fruit generously for the benefit of many.
The image of the soil can evoke the reality of the family, on the whole good; the sometimes arid and harsh environment of work; the days of suffering and tears. The earth is above all the heart of every person, especially of youth, to whom you address your service of listening and guidance: a heart that is often confused and disoriented, yet capable of containing unimaginable powers of generosity. It is like a bud ready to open to a life spent for the love of Jesus, able to follow him with the totality and the certainty that comes from having found the greatest treasure that exists. It is always and only the Lord who sows in human hearts. Only after the abundant and generous sowing of the word of God can one progress further along the paths of companionship and education, of formation and discernment. All this is linked to that tiny seed, the mysterious gift of divine Providence which releases from within an extraordinary force. In fact, it is the Word of God who brings about in himself what he says and desires.
