You need to remember the Prodigal Son never HATED his Father!
The people Paul was refering to HATED God in their hearts after receiving the Holy Spirit. Once you do that then basically the Holy Spirit will leave you and that person cannot be brought back unto repentance! It also crosses the line into the unpardonable sin. This person before he reaches this state should be turned over to satan for the destruction of the flesh that he might be saved during the day of Judgement otherwise he will burst the gates Hell wide open!
See the parable of sower for a reference
But the Holy Spirit remained with the Prodigal Son and protected him from himself. Remember these points! The Holy Spirit kept him from crossing the line on numerous occasions and brought him safely back home after the lesson was learned! He always loved his Father! The Greatest Commandment Jesus Christ gave us!
Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment.
