Blood represents life, death, guilt, or atonement
Here’s what it means
Blood can stand for life, violent death, bloodguilt, sacrificial death, or atoning provision.
Why the Bible says it this way
An idiom is a familiar phrase whose meaning comes from the whole expression, not from reading each word by itself.
A helpful detail: The range must be controlled by context. Figurative or metonymic use never makes Christ’s shed blood and death unreal.
