He dismissed His Spirit? No, not really. He was a man, flesh, just for everyone, even for me. He lived and was cricified as a man so that no flesh might fault Him forr being the true Jedge.
He did have the Father dwelling in Him. He was raised by the Father, and after He was raised He was being florified for 40 days until He ascended. He is God, and He is the Father, and He is teh Holy Spirit, ask Isaiah, but while He was alking His erth, He weas a man.
He is the first born of the resurrection, yet He is the resurrection. Do not attmpt to even hint that you , I or anyone can explain how the Father, the Son and the Holy Spirit are yet One, for this mystery is privileged information until the ingdom.
