The seed is God’s word. 12 The seeds that fell on the footpath represent those who hear the message, only to have the devil come and take it away from their hearts and prevent them from believing and being saved. 13 The seeds on the rocky soil represent those who hear the message and receive it with joy. But since they don’t have deep roots, they believe for a while, then they fall away when they face temptation. 14 The seeds that fell among the thorns represent those who hear the message, but all too quickly the message is crowded out by the cares and riches and pleasures of this life. And so they never grow into maturity. 15 And the seeds that fell on the good soil represent honest, good-hearted people who hear God’s word, cling to it, and patiently produce a huge harvest. (Luke 8:11–15).
This is Jesus' explanation for the parable of the seeds. It is about the different ways people respond to the message of Christ. I believe only the last person described is a genuine follower of Christ headed for eternal life.
Many people make professions of faith that "don't stick." In other words, they are caught up in a moment and respond. However, that faith is not based on a true desire to trust and follow Christ, it is a desire to act on the emotions of the moment.
People may spend all their lives thinking the "experience" they once had is all that is needed. Jesus said, the only true believer is the one whose life is surrendered to Christ and therefore begins to change in their thinking and living.
The key question is: which kind of response to the gospel describes you?
