Here is what I would recommend. Put the gentlemen in any room in the house and fill it with noisy children. Turn on the blender, have a plane fly overhead, construction workers working outside, and then ask them if they happen to overhear the little transistor radio in the other room that has the IU basketball game on. I can spot Don Fisher's voice from three rooms away. Then you will find out men's ability to hear and to listen.
Advent is about learning to listen.
I suspect that whether we listen with one-half or all of our brains, sometimes we find it a challenge to truly hear what is being said. We filter out the things that don't match with what we expect. We filter out the things that don't match with our own preconceived notions and ideas, and we put filters on even when we hear the words of scripture. We assume that we hear and know exactly what they are saying and where they are leading us. But if we listen in Advent with fresh ears, what we will discover is that there are surprises along the journey.
