An Internet site defined “packed red-blood cells” as, “a preparation of red blood cells that are transfused to correct low blood levels in anemic patients.”
Packed red blood cells can also be given to other patients whose hematocrit, or concentration of red cells in the blood is low because of diseases like cancer, or in blood loss from accidents.
One unit of packed red blood cells transfused will typically raise the hematocrit three to four percent and the blood hemoglobin concentration by one gram per deciliter. Since hemoglobin is the chief oxygen transporter to the cells, raising its concentration increases the amount of oxygen delivered to the brain and body.
In the book of Colossians, the apostle Paul equips the body of Christ to deal with error and division that had arisen from people who believed they had some special kind of knowledge. In the second chapter, he provides the church with ways to defend itself against the assaults to come.
He begins with encouragement. The world seeks to break down children of God; therefore we must find ways to build each other up. Like cells in the body are packed together and concentrated building up the body, encouragement is like that preparation of packed red blood cells to build the blood.
The apostle tells members of the church in Thessalonica to encourage the “fainthearted” or the ones with small souls (1 Thessalonians 5:14). The aim, of course, is to make bigger, stronger souls.
From encouragement, Paul discussed another aspect of the same idea: that we should be “knit together in love.” This is the mortar that binds us together under our Lord’s direction. Just as a surgeon draws together an incision into one piece, we are drawn together in love. The apostle wrote that love is the bond of perfection in Colossians 3:14.
But love without true wisdom and knowledge is not enough. “Love without knowledge is like heat without light,” Spence and Excell wrote. Paul encouraged the Phillippians that their “love may abound yet more and more in knowledge.” We must always want to increase our knowledge of Jesus, for his is the true knowledge (Colossians 2:9; Ephesians 4:12-13).
If we accept the prescription given through the word of God, we can live in the assurance of a healthy spiritual life in Christ that can fend off problems and ensure the “unity of the spirit in the bond of peace.”
