The parable of the sower is in the Mass readings these days. I was reading a commentary by Fr. Harrington, SJ, and he made a good point about the sower. The sower sowed the seed in some places that seemed quite unlikely: the path, the brambles, the rocky ground. Is there any point to this? Father didn't go into it too much, but it got me thinking.
Maybe it's meant to indicate God's lavish way of bestowing graces on us. He gives grace everywhere, to all of us, even when it seems like he's just wasting it. Why throw seed on a thorn patch? Why lavish graces on sinners? Yet, God does it. He's always giving us a chance, even when we seem to not want it and are more likely to reject it than accept it.
The prodigal sower is a good figure for the God who gives and gives, and--let's be honest--gets very little response in return.
