The seed falling among the thorns refers to someone who hears the word, but the worries of this life and the deceitfulness of wealth choke the word, making it unfruitful.
“Be careful, or your hearts will be weighed down with carousing, drunkenness and the anxieties of life, and that day will close on you suddenly like a trap.
The seed that fell among thorns stands for those who hear, but as they go on their way they are choked by life’s worries, riches and pleasures, and they do not mature.
Still other seed fell on good soil. It came up and yielded a crop, a hundred times more than was sown.” When he said this, he called out, “Whoever has ears to hear, let them hear.”
