I routinely 'give blood' at least 4-5 times a year. It's when I go to my doctor. So do most jw's when they have several vials of blood drawn and sent to some laboratory to be analyzed and checked to determine their health especially when looking for a specific marker in their blood. So it's okay to 'donate' blood when it's going to be used (analyzed in a lab) to help the medical profession determine if a faithful jw has some medical condition that may be treated and prevent their death?
But if death is staring a faithful jw in the face and administering blood id the only alternative the medical profession has to save their life, blood suddenly becomes sacred?
just saying!
