I asked the same question based on this scripture :
LUKE 15 : 7 says : -
"I tell you that thus there will be more joy in heaven over one sinner that repents than over ninety nine righteous ones who have no need of repentance."
Within the organization, the requirements for Reinstatement of those who are Disfellowshipped are 'repentance' of any any previous actions and attitude ; a demonstration of no longer practicing whatever 'sin' you got disfellowshipped for, as well as demonstrating submissiveness to the Elders, the Regulations, and the F&D Slave. Only after all of this can a person be reinstated back into the 'Fold'.
The scripture plainly states that within heaven itself, a sinner who repents is regarded MORE than a righteous man with no need of repentance. The joy expressed is FAR GREATER for these ones, and where they stand , the righteous cannot stand. They are loved and desired by the Creator as if they had never sinned at all. The Pharisees as we know were forever critical of Jesus and his efforts to bring people to God, and this scripture was nudging them and letting them know that they should have been fully engaging themselves and co-operating with his efforts.
