Thanks Bobcat for your reasoning. When I read it something seemed to dawn on me and I wonder if it may be a reasonable thought (and I apologize as I find it difficult to express my thoughts but here goes -
To be baptized with the Holy Spirit is a realization that we have made ourselves acceptable/approved for the giving of the gift from God, which is the prospect and the possiblity of everlasting life which was made possible through the sacrifice of Jesus Christ. By realization I don't mean that we personally are aware that we have suddenly been given this gift but by our belief we have made ourselves available for this gift. It's like a missing link in that God required mankind to be redeemed, Jesus offered this redemption and all that is now required is for there to be faithful followers to whom the benefit of this gift can now be given. So the prospect of everlasting life (and the restoration of perfectness) for individuals is not possible unless God's holy spirit can be bestowed on them.
Being anointed by Holy Spirit was not possible before Jesus came to sacrifice his life as there was no permanent redemption of sin up until this time.
The problem with this thought, though, is that people were being anointed with the Holy Spirit before the actual sacrifice was made by Jesus.
I may be way off track so I would appreciate your opinions.
