As I said earlier, the Bible says that the life of the flesh is in the blood. This can not mean that a man can only loose his life if he loses his blood, because a man can die in his sleep without ever losing a drop of his blood. It means that the SPIRIT of a man which is the life, is in the blood as in resides in our sacred blood.
Lev 17:11 For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul.

13 And whatsoever man there be of the children of Israel, or of the strangers that sojourn among you, which hunteth and catcheth any beast or fowl that may be eaten; he shall even pour out the blood thereof, and cover it with dust.
14 For it is the life of all flesh; the blood of it is for the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh: for the life of all flesh is the blood thereof: whosoever eateth it shall be cut off.

That is why Abel's blood cried out, that is why when we are born again, it is by the Spirit of LIFE that indwells us now making us of God's family. That is why blood sacrifices of animals were made for atonement, that is why we are not to exchange blood, nor eat blood, and blood is to be buried as God had the earth to open up to cover his blood.
