I helped out Bunker Hill Lutheran Brethren Church this past Sunday. I preached on the Parable of the Sower. It was hopefully a good reminder of the kind of soil we were and the kind we become, by no ability of our own. Give it a listen and let me know what you think.
ALSO: part of my mindset in preaching on this passage comes from the perspective found in this short book on the parables. You should give it a look!
