If you are claiming that the third Person of the Holy Trinity was Jesus's human spirit, that is a heresy called Apollonarianism. It was condemned by the second Ecumenical Council (Constantinople, 381 AD).

Indwelling Jesus's human spirit was/is the Holy Spirit of God. I would never claim a human spirit is God, but your human spirit may have God's Holy Spirit come into it to transmute LIFE into you. As Jesus was located in time and space, the timeless aspect of His Spirit indwelt His human spirit, the spirit inherited when He took upon Himself a tent-tabernacle of flesh.
Unlike our adamic state, with a human spirit void of LIFE, Jesus had a human spirit ALIVE with The Spirit of God. It was this Spirit which left Him at calvary, leaving the human to die in our place, It was The Holy Spirit Who raised Him from the dead by coming again into His human spirit. IMHO, that's why the negative image is found on the Shroud, because the Light of LIFE came from the inner to the outer, quickening the body wrapped in the Shroud.
