'Blood' in the Bible

The cup of blessing which we take, does it not give us a part in the blood of Christ? and is not the broken bread a taking part in the body of Christ?

In the same way, with the cup, after the meal, he said, This cup is the new testament in my blood: do this, whenever you take it, in memory of me.

If, then, anyone takes the bread or the cup of the Lord in the wrong spirit, he will be responsible for the body and blood of the Lord.

Now I say this, my brothers, that it is not possible for flesh and blood to have a part in the kingdom of God; and death may not have a part in life.
