The Good Seed

When I was in Chile, I had a holy, prophetic and courageous priest for my spiritual director. One of the wise things he told me was about today's Gospel. It was easy for me to identify with the seed 
that did not fall on good ground. But what was the good seed that fell on good ground and took root? 
He said that those who recognized themselves in the seed that fell on the path, on rocky ground, and among the thorns, they are the ones who are able to hear the word and accept it and bear fruit!
The seed is always good since it is God's word and we are the ground it falls upon.
