The Spirit of Christ and the Holy Spirit

The Apostle Paul says that the spirit of Christ and the Holy Spirit are one and the same. When we're created when we're born, we have an animal spirit or you could call it a a fleshly spirit or something like that. And then through baptism they receive the Holy Spirit from a particle of the Godhead,. It is not against subject to death. So again, there is something preaches us about Jesus, but it's only spirit.
