Today many students can capture
a concept more easily visually than through the written word. The use of an appealing
visual aid can clarify truth, but such aids should not be used
to entertain or draw attention to oneself. An effective visual
aid is like a hook in the mind to which truths
could be carefully secured so that it can be
understood, remembered, and used in time of need. Such aids should be conditioned
to the age of the student. They may need to be
understood in the context of his environment. Jesus is a master at the
use of such visual aids-- grain of mustard, a child,
a millstone, a roman coin. He forever confirmed
their power.
