All in Between Callings

We are all moved to work diligently for the kingdom when we are in the middle of an active calling, but how do we spend our time after God has called us out, after a calling is complete, and we are praying for God to reinsert us into his service? Is this simply a time of rest, do we give up and put our faith on the shelf, or maybe we find ourselves unsettled, despondent, or impatient as we cry and ask for a new assignment?
