Matthew 13:19 speaks of those who hear the Word, but do not reflect on it—they are snatched away by the evil one. They do not understand it, and this becomes their downfall. The reason is not that they are unable to understand, but that they make no effort to understand. And in those who are unwilling, Satan can do his work; he will immediately snatch away the word.1
19 When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart. This is what was sown along the path.
