Mark 4:16-19

And what is sown on gravel represents those who hear the message and receive it joyfully, but because their hearts fail to sink a deep root, they don’t endure for long. For when trouble or persecution comes on account of the message, they immediately wilt and fall away. And what is sown among thorns represents those who hear the message, but they allow the cares of this life and the seduction of wealth and the desires for other things to crowd out and choke the message so that it produces nothing.
