Doug Groothuis has a blog called The Constructive Curdmudgeon. He is a philosophy professor at Denver Seminary. He posts fairly regularly, and has some interesting things to say. He will occasionally make some of his outlines available if you will email him. He has an apologetics class online that you can download and listen to. He is not a presuppositionalist, but still has some good stuff. He is an egalitarian and a supporter of intelligent design.
Having said all that, here is one post that I found particularly intriguing and thought-provoking. It is a list of forty-nine propositions or imperatives. Most deal with matters of spiritual life and leadership.
You will also learn that John Coltrane is the greatest saxophonist of all time and that Kenny G is a crock whose success is evidence of a fallen world (nos. 38 and 39).
Apart from that, you will also see some things that are actually challenging and thought-provoking. Take the time to read and consider all forty-nine.
