The strengths and weaknesses of radio

I have to bear in mind that the radio show is not a classroom.

Things that work well in the classroom do not translate into the radio format.

In the classroom	On the air
"Silence is golden."	Silence is dead air.
I have the same students, day after day. I expect them to remember the last class and plan on seeing them again to follow up on this class.	Every unit must be self-contained. It has to stand on its own legs because the listeners come and go as they please. I have to supply--briefly!--whatever is needed to understand what I'm saying when I'm saying it.
I can correct and augment what I am saying through body language, homework assignments, handouts, and the use of the chalk board. We can read texts together and long pauses while the students struggle to answer questions about the text are very appropriate for the classroom setting.	Our listeners listen when, where, as they can. I cannot expect them to follow complex exegesis. Keep it super simple!

The beauty of radio is the willingness of listeners to listen. It is a free choice, unencumbered by requirements for a degree, term papers, and final exams. People listen because they want to hear about Jesus. Their hearts and their minds are open to God in a very special way. God sees the secrets of their hearts and can do what He wills with the seeds that we sow.
