When people hear the message about the kingdom and don't understand it, the evil one comes along and rips out what was sown in them. This is what happens to the seeds sown on the path.
The seeds on the path where the word is sown illustrate those who hear the message, but then Satan immediately comes along and takes away the word that's been sown in them.
Other seeds fell on stony ground where there wasn't much earth. In the shallow soil the plants started growing quickly, but because the soil wasn't deep
The seeds that fall on the road are those who hear the message, but then the devil comes and steals away the truth from their minds so they won't trust in God and be saved.
