Something was changing that's for sure!
The anointing would not have been possible if that were not true.
I contend that the change was incomplete until he was filled with the Spirit.
Titus 3:5-6 ...but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior,
I am equating "saved" with regeneration and conversion in Paul's writing to Titus.
We are addressing this academically, and I realize there will be diverse views to an extent.
I believe the Holy Spirit lives within us. Without it there is no compulsion to do right.
When Saul was moved to do right, it was only possible because the Holy Spirit was already within and working on him.
I don’t seek to diminish the anointing and would equate it in relative terms to baptism. It would be a formal act of something that had already taken place. In the case of baptism, I would term it something that had to take place, so I don’t want to make it seem I think it’s is a mere formality. I see it as a very important significant act.
Anointing, not quite to that level. I do think it is a worthy act too.
