You have not shown that blood is not sacred to God. You have only shown in your argument that blood from a creature that is not slaughtered for food should not be -based on your argument.
Blood is sacred to God, but only after a life has been taken. The blood flowing through the body of Jesus had absolutely no benefit to humankind while he was still alive. It wouldn't have mattered how many gallons of his blood he potentially could have offered up. It was only through his death that his blood took on any sort of real significance in the eyes of God, Ephesians 1:7.
Fisherman there is a big difference between you believing that all blood is sacred and God viewing it as so.
God's viewpoint on the sacredness of blood is clearly outlined in scripture. His viewpoint is both logical and loving. Your viewpoint is clearly outlined in the watchtower. Who should I trust? Have the watchtower provided me with a proven track record of having always presented information in an accurate and honest way?
