This is spiritual. It is about faith.
A person who does not consider the value of the broken body and shed blood does not appropriate the blessings that they provide.
By His stripes we were healed.
By His blood all our guilt is removed.
Those who do not consider the broken body are NOT healed.
Those that do not consider the shed blood REMAIN under guilt.
Not being healed is poor health.
Not being set free is bondage.
Bring unhealthy and in bondage is death.
The bread and the wine are symbols of the body and blood of Christ which was broken and shed ONCE FOR ALL TIME.
