Jesus refers to some hearers as thorny ground. Jesus said that some seed fell among the thistles and the thorns. The plants began to grow, but so did the weeds. As the thorns grew they choked out the plants.
Jesus told his disciples that the word is sent forth and some people accept it with excitement; however, as soon as the seed has grown it is choked out by the cares and worries of life.
Do you allow the cares of life to choke out the enthusiasm that you have for the Word of God?
