I am a Christian but not aware of this. Thanks for this revelation. From your insights, it is clear that the spirit indeed Was The flow and what gives life. The blood was introduced which now is the working flow that gives life to the mortal body. In order words:
Spirit - immortal
Blood - mortal.
No wonder a man dies when he loses blood.
Same vein a child of God who is to live by spirit dies and become ordinary when he is no longer in tune with the spirit.
Thank you so much for such an insight
