How could the 'certain man' have kept his son from going Prodigal ?
Jesus never chased anyone. As hard as it is for Christians to understand, God respects people's choices and so should we.
Stop chasing people who do not recognize the Gift of God . Find those who are thirsting and hungering for God . Those are the ones who can and will be filled.
When a person goes Prodigal rest assured they will end up in the swine pit. At that point their eyes will be opened and they will return to God .
Trust God with the rebellious. Spend your time looking for the ones God is dealing with. They will be receptive.
