Eating human flesh or any blood is forbidden by #torah (God's Law). God promises death to those who do it. Life/nephesh is in the blood and the misuse of blood is a terrible sin per Genesis 9, Leviticus 17, and Isaiah 66.

Q: Why did #yeshua (#jesus) say that we will have eternal life if we eat his flesh and drink his blood in John 6:53-58?

A: All men die and their nephesh returns to the earth from which it came. All men, except Yeshua. There is eternal life in Yeshua's blood. When we repent and submit to Him, his blood covers our sins. Yeshua's life is imparted to us by his broken body and shed blood, which is from heaven, not earth. His incorruptible nephesh infuses us. Ours returns to dust, but His carries us onward to God.

When Yeshua said we must eat his body and blood, he didn't mean it literally. He meant it metaphorically, that we must allow his death to become our life.
