Let's see if I understand you correctly.I did not say the same spirit that was in the man Jesus doesn't also indwell within the saved.
I don't think saying the Spirit of GOD that was wholly in Jesus should be called Jesus explicitly today as it refers to the man Jesus and doesn't focus on the Spirit of GOD but the man that the Spirit filled.
Do you agree or not: I believe all humans have a flesh body and their own spirit that lives inside of them. I believe that Jesus' Spirit is the Holy Spirit.
Not sure why you have 'an angel of the LORD' as part of this discussion about God being Spirit.Also; saying the Spirit of GOD/ GOD/the Holy Spirit/ an angel of the LORD/ Lord GOD was the fullness of the Spirit of Jesus the man isn't the same as saying the man Jesus was the literal fullness of GOD as a man, but as can be perceived by man.
It is written that none can observe the fullness of GOD. That isn't to say at allbthat GOD is incapable of whatever is IT'S Will.
So you think that the spirit that filled Jesus is the same One that indwells true believers?
I believe Jesus' Spirit is the Holy Spirit and it is the Spirit that all the saved receive to live in them.
