Josh Harris loves the local church...

...and therefore he's seving those who preach in the church by gathering sermon manuscripts from a range of preachers. It's notable that each takes very different notes into the pulpit.... Dever's typed with some highlights and bolds plus post-printinng scribbles is most like mine, though I would often whack the font size up to 20, landscape paper with 2 columns. Bullmore on the other hand has almost illegible handwritten notes.There is no definitive way to do this. Let us learn from one another.More considering content than paperwork, see The Biblical Theology Briefings - sermon manuscripts with the preacher editting back in his logic for what he said, why he said it etc. And Colin Adams shows that there is something to learn from every preacher.
