The disciple with a stony-soil heart makes an emotional response and lacks strong convictions. It is easier to become a Christian than to practice Christianity. A plant cannot survive that is not adequately rooted. The plant that begins to grow where thorns or weeds also grow, unsuccessfully competes for space and resources. The seed was not purposely sown in the weeds, but the weed seed was present in the soil when the good seed was planted.
Weeds grow naturally.
The good seed did not have enough room to grow. Therefore, it died and obviously was not fruitful. Had the thorny soil been properly prepared, it could have produced a bumper crop. The thorny-soil heart, though he responds to the Gospel, is preoccupied with the influences of the world and materialism. A thorn is anything that crowds Jesus out of our lives.
