I've got a series of sermons, partially written, that I've never given.
They're originally written to be given as part of a revival.
I first got the idea to write them when we lived in Orlando, and I was going pretty hard at BASIC. At the time, I was studying 1 John, and thought, "WOW, I could write five sermons from this book as a revival series!" I quickly hammered out the general ideas for all five sermons, then started writing outlines. The first two outlines came easy, I had to revise the third a few times, and I've not written the fourth or fifth. Every couple of months, I tell myself I need to finish it. I'm not in demand as a revival preacher right now, I don't even teach a Sunday school class, but I've always told myself that if I finish these lessons, I'll have done something.
I'll get started on that fourth sermon sooner or later, I've been having the itch to write it again. Just need to reread 1 John. That book always convicts and encourages me.
