God among our Family and Friends

Why did Jesus in Mark 6:4 say that a prophet is honored everywhere except locally among family and friends? A theology professor once commented that if relatives think you're weird or nuts, you may just be a preacher of the Gospel. What is it about being an out of towner that makes a person seem more authoritative than someone that we all know very well? Why does a native create so much disbelief and scoffing in other locals? Is that why people travel to faraway conferences and send money to distant evangelists while local ministries are neglected? Do we simply believe that God must be far away rather than that he will use local friends and family in powerful ways. God is doing marvelous things right in our own backyards. Let's not miss out because of unbelief. Let's look for and discover what God is doing among family and friends.
