JOY-SUCKERS
A "joy sucker" is someone who is determined to create either discouragement or hardship on your ministry. "Joy suckers" take on all shapes and sizes, but most often they are negative in their outlook, disappointed with their family, in need of attention or enamored with their own power. Somewhere along the way, they have been allowed to get away with unacceptable behavior.
Because they are not happy people, they are determined that others should not be happy either. So, they are critical, fault-finding and contentious. Close your eyes for a minute, and you will see every "joy sucker" you have ever served. Painful, isn’t it?
