The blood flowing in our veins is the world's most amazing medicine. Blood, and the medicines made from blood, are saving more lives than any one drug that science has ever discovered, and there is still much to learn in how to use blood in the fight against disease.

Blood has always fascinated man, and he has been prying into its mysteries for centuries.

In the year 1628, William Harvey, an English scientist, discovered that the blood was a "river of life" flowing around in the human body, and shortly thereafter, physicians tried for the first time to replace lost blood with the blood of other humans, and also animals. Often the patients died, but occasionally a life was saved. However, failures were so common, that during the seventeenth century, laws were passed forbidding transfusions of blood.

It was in the year 1900, that a German scientist, Dr. Karl Lansteiner, discovered that there are four different kinds, or groups, of human blood. This unlocked the door to successful blood transfusions, for it was learned that if blood from a donor of one of these groups, was given to a patient of the same group, no harm could be done. Thereafter, many blood transfusions were made, and many lives were saved.

However, it was not until 1915, when two American scientists, Peyton Rous, and Joseph R. Turner discovered a solution which, when mixed with blood, would keep it from clotting.

Now, blood could be preserved or "canned" for emergency and future use, and the first blood bank was established by an English army surgeon Oswald Robertson, back of the Allied army lines in France in 1917, resulting in what we have today in the various community "blood banks," which are endeavoring to serve their area day and night, which have as their slogan, "BLOOD IS LIFE"-"HELP SAVE A LIFE. Yes, "blood is life," and this truth is verified in God's Word.

"For the life of the flesh is in the blood I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul (Leviticus 17:11).

The greatest subject in the Bible is the blood which is the very life of the Christian faith.

And that brings us to the subject to the "World's greatest "blood" Donor," and none other than God's own Son, the Lord Jesus Christ, who willingly and sacrificially gave blood, so that poor guilty sinners might have eternal life.

As sinners, (and let us ever bear in mind we are ALL sinners in God's sight) we fully deserve punishment and death, for "The wages of sin is death" BUT - "The gift of God is eternal life through Jesus Christ our "Lord" (Romans 6:23).

It was the Lord Jesus Christ, who voluntarily gave Himself, suffering the cruel death cross, and who permitted Himself to punished in our place, and who offered His life's blood for us, so that we might have lasting life through Him.
