Sometimes I wonder that about my writing...and the media...especially right now.
If there is no one around to read or listen...is there really a message? Or if only the people that agree with you are your readers or listeners...do you really make a difference?
One human did make a difference way back when. A wilderness wind carried a message from a strange soul to a scared and hungry people. A prophecy was fulfilled. People were strengthened. A King was revealed. A difference was certainly made.
Isaiah 40:3 - The voice of one crying in the wilderness: "Prepare the way of the Lord; Make straight in the desert a highway for our God."
