Life is in the Blood
Blood is made up of protein and cells that help keep us alive. The average human holds
about 5 liters of blood in their body. Blood consists of erythrocytes, leukocytes, and platelets
from the blood. The rest is made up of plasma. Erythrocytes contain the pigment which gives
the red color to our blood, and it also transports carbon dioxide and oxygen to and from the
tissues. Leukocytes are in charge of fighting against diseases. They are also known as white
blood cells. Platelets are pieces of giant cells in the bone marrow that help form blood clots to
slow down or stop the bleeding from wounds. Plasma is the most significant part of the blood
that makes up more than half of the content in the blood. It consists of ions and electrons,
which are essential to the blood.
Blood is essential to the body, but it is vital to function because life is in the blood. All life
belongs to God. He is the one who created. At first, only a spotless animal's blood could cover
the sin we bear. Thankfully, according to John 3:16, that has all changed. John 3:16 tells us that
God sent His Son to shed His blood to cover all of our sins and will commit them. Because of His
blood, we can enter the throne room of God. John 1:7 tells us that because of Jesus' blood and
sacrifice, we will have fellowship with one another because His blood cleanses us from all sin.
Another example is in the Lord's supper. Jesus tells his disciples to take the bread as His body,
break it, and drink the wine as it is His blood (Matthew 26:27-28). God is life. He is the source
and the creator of it. We have life because he created blood, and because He shed His blood,
we can have life eternally.
