Salvation according to Apostle Paul.
4 But after that the kindness and love of God our Savior toward man appeared,
5 Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
6 Which he shed on us abundantly through Jesus Christ our Savior;
7 That being justified by his grace, we should be made heirs according to the hope of eternal life.
Two points important for us – outpouring the Spirit on person abundantly and regeneration with renewal.
If God shed the Spirit through Jesus on person -person feels the influence of the Spirit,it happens immersion or baptism.
If person starts to believe, repents -it is not outpouring of the Spirit on person and not regeneration.
And opposite- if person starts talking in tongues or gets some other manifestations of the Holy Spirit – it is not regeneration and renewal. These ones should happen later on.
We could tell here that baptism/immersion into the Holy Spirit just started. Will it be continued or interrupted – it depends on person.
Will a person be born and renewed after baptism or immersion and how many immersions needed – depends on person.
Regeneration means to be born again/from Spirit/from God and the result -to become spirit.
As the birth by flesh produces flesh and in flesh one comes into visible world, so with the birth from Spirit,it produces spirit and spirit comes into invisible world-why who is not born from Spirit cannot see the kingdom of God.
We stopped to be spirit being in Adam when Adam eyes opened to see evil.
After regeneration we need renewal. Renewal means to become new man/creature inside. New man it is that man where Jesus Christ everywhere. That state is perfection.
