From whom does the most pressure/persecution come from? Those just described as the wayside. Those here now without root expect peace and pleasantry. If the gospel is obvious to them it should be obvious to others they presume, and yet it is not obvious, ridiculed, divisive, persecuted against, even deadly. The young fledgling becomes disheartened, embarrassed, offended. A process - sunlight that is supposed to bring about growth instead kills off the plant. Though passive from ther out typically by number they are used by the wayside (therefore Satan) to increase the pressure on the remaining believers.
