Do you know what
nephesh is?
It's not some "force" in the blood. It's a person's soul, their inner essence of being. Since this inner essence of being is in the blood of all humans, and even in animals, to a degree, when blood is shed, this inner essence is lost, hence why the physical body dies if sufficient quantities of it are lost (Also, it's why murder [shedding of blood] and the drinking and eating of blood was strenuously forbidden by Torah code of conduct).
Jesus died of cardiac arrest due to massive hemorrhage brought on by trauma and shock.
When this happened, more than just liquid poured out. His inner essence of being, what is considered His soul in
Isaiah 53:10, also departed His flesh, when He died. It was this soul, that the Father would not leave in Sheol (See
Psalm 16:10 and
Acts 2:27), this inner essence of Christ's being, that propitiated the Father, since it was a life lived in perfect obedience, submission, and humility, even in death.
This same inner essence of Christ's being is imparted to us when we receive the Spirit of Christ (
Romans 8:9), or Spirit of God's Son (
Galatians 4:6). This is why the Spirit is life, because of righteousness (
Romans 8:10). Because of Christ's righteousness, His Spirit imparts new life to us--HIS LIFE, gained again by the glory and power of the Father when God raised Jesus from the dead.
