How many of us aren't familiar with the miracle of a blood transfusion? It's the method of transferring blood from one person to another. Through this physical process there is literally a transference of life. Recognizing this physical phenomenon, we shouldn't think it strange that blood should be associated with spiritual life given to us through the atoning death of our Lord Jesus.
LIFEBLOOD
Life--that mysterious quality which science has never been able fully to define--immediately brings to mind the blood. This vital fluid courses through the flesh of us all, bringing the food and oxygen which sustains bodily functions. The blood also fights disease that enters the body and assists in getting rid of waste products.
In an average human being, it circulates twice every minute. As the heart pumps the blood through the network of arteries, capillaries and veins, every cell in the body is continually supplied and cleansed. No part of the flesh can live without being in contact with this Red Stream of Life!
Truly it is amazing!
Though medical research has probed deep into its mystery, there is still locked within its elements a secret known only to the Creator. Yet, whatever remains hidden it is clear that the blood is the essential ingredient of physical life. In a very real way life becomes visible through the blood.
We can understand then the Bible's speaking of "blood of your lives" or "lifeblood" (Genesis 9:5; 1 Chronicles 11:19; Isaiah 63:3). The phrase "born of bloods" conveys the same idea of human life (literal translation of term in John 1:13; and Acts 17:26). There are rare occasions when the words blood and life can be used interchangeably, as in Leviticus 19:16 when we are told to "stand against the blood" of our neighbor. Here blood clearly refers to the man's life, and is so translated in some versions (RSV, NASB).
In the same vein, since the heart is the center of the blood circulatory system, it becomes the ideal example of life. The term is used in this way hundreds of times in the Bible to designate the total personality of man.
Because of this it can be said that out of the heart proceed evil thoughts (Matthew 15:19); sinners should rend (tear) their hearts (Joel 2:13); we must believe with our heart (Romans 10:10); or God will take away the stony heart and give a new heart (Ezekiel 11:19).
Dr. Christian Barnard, who, in 1967, performed the first human heart transplant in history, tells of one of his heart-transplant patients asking to see the removed organ. Dr. Barnard had hospital staff bring the large bottle from the lab where the old heart had been placed. As the man looked at the big muscle which once pumped life through his body, the famed surgeon suddenly realized that this was the first time in human experience that a person had ever seen his own heart.
It was indeed an historic moment. But for the patient the sensation must have been even more moving, for the old heart was worn out. Had it not been replaced, life would soon have been extinct. After a long pause, the grateful man looked up and said, "I'm glad that I don't have that old heart anymore."
Certainly, we are no better than our heart, whether it relates to the body or the soul. Where the heart is weak and the blood diseased, life is in danger. But where the heart is strong and the blood is pure, life is full of health and overflowing with joy. This is what Christ wants to give to every person.
What can wash away my sin?
Nothing but the blood of Jesus;
What can make me whole again?
Nothing but the blood of Jesus.
Oh! Precious is the flow
That makes me white as snow;
No other fount I know,
Nothing but the blood of Jesus. ---Robert Lowery
