Half-Duplexing. Have you heard that term? Chances are good that even if you’ve never heard of it, you have first hand knowledge of what it’s all about. Something similar to this was taking place back in Samuel’s day in the Old Testament. And, for good or for bad, it's a term that can easily be used to describe our own communication with God. What is absolutely amazing is that we have a loving God who wants to speak to us in mercy and love.
