If one wishes to be completely overwhelmed with complex information, one simply has to Google TASKS OF HUMAN BLOOD. I was amazed by just a cursory study of those tasks. The blood: delivers nutrients and oxygen to cells; transports waste from cells; maintains homeostasis; (ability to adjust the internal environment to maintain a stable equilibrium) transports hormones, regulates body temperature; clots to stop bleeding; and has many more complex functions. Its components are just as varied being made up of: plasma; proteins; lipids; glucose; red and white cells, and platelets.The total amount of information was far beyond my feeble intellect, but made me better understand the scripture that, “…the life of a creature is in the blood..” (Lev 17:11) It also reinforced my belief that such a wonderful and complex system could not have slowly evolved but had to be the creation of a master planner.
Is it any wonder that when Jesus tried to explain the spiritual application of his blood that many disciples turned back and no longer followed him. (Jo 53-66) He had said that, “Whoever eats my flesh and drinks my blood remains in me and I in him. (v 56) He was speaking, of course, of the words he was teaching. (v 63)
However, the physical blood that Jesus sacrificed was: precious; (1 Pe 1:19) justified us; (Rom 5:9) redeemed us; (Eph 1:7) brought us peace; (Col 1:20) atoned for us; (Rom 3:25) created a new covenant; (1 Cor 11:25) and freed us from our sins. (Rev 1:5)
When we gather around the Lord’s table each first day of the week (Acts 20:7) to partake of the Lord’s Supper (1 Cor 11:20-29) we should remember his physical blood that he shed as well as the spiritual words of his teachings. This is much more than a ritual. We are told to examine ourselves before drinking of the cup and recognize the body and blood of the Lord. (1 Cor 11:28) If we lose a lot of physical blood we need a transfusion. In our spiritual life there are times we need to refuel with Christ’s words.
