I've often thought of this Gospel in terms of me being the seed, but what if this parable is about me being the ground. Do I provide a rocky terrain for the spiritual seeds of those around me? Do I choke my neighbor's seeds of spiritual growth with thorns of worldly concerns? What sort of environment am I creating for those whom I meet?
I would like to think that I can guide people to spiritual nourishment, but I tend to be rather rock-headed myself.
