how many Christians are revealed in the parable of the soils?

1. One hears the word, understands it not, and it is taken away.
2. One hears the word and is glad but the word causes affliction and persecution and he immediately falls away.
3. One hears the word but the worry of the world and deceit of riches strangles the word and it becomes unfruitful.
4. One hears the word and understands it and he indeed bears and brings forth fruit.
