When I was in the USCG we were once lost in NY harbor. Our compass had been removed for recalibration. Heavy fog had sucked in and all of NY harbor was down to about 100 feet of visibility. So there we were between Brooklyn and Staten Island, lost unable to navigate, unable to fulfill our purpose all we could do was run in circles.
Isaiah reminds us that we are all once like that, lost if a fog of meaningless and purposelessness.
