'Blood' in the Bible

The cup of blessing which we bless, isn't it a sharing of the blood of Christ? The bread which we break, isn't it a sharing of the body of Christ?

In the same way he also took the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink, in memory of me."

Therefore whoever eats this bread or drinks the Lord's cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord.

Now I say this, brothers, that flesh and blood can't inherit the Kingdom of God; neither does corruption inherit incorruption.
