Have you ever been asked to care for something of great value - something very precious to someone else - something that could not be replaced? It is a very great responsibility, one invoking great trust in your ability to act and think correctly in regard to the position you would find yourself in. To me, it would seem a humbling experience, to think that somebody would consider me trustworthy enough to entrust their special masterpiece in my care.

You and I have been entrusted with the greatest masterpiece in the world! It is a most wonderful mechanism with a structure so intricate, so flexible, so strong as to baffle scientists and engineers as they try to copy just some of its functions. It is the most complex, interesting, awe-inspiring creation that anyone has ever seen or made. It is definitely a masterpiece!

The telecommunications network of this mechanism cannot be matched by anything on this earth and can reach as far as the heavens. This mechanism is complete with more than the most advanced systems in lubrication, ventilation, elimination, production, manipulation, warning, and temperature controls, to name just a few.

This masterpiece, in case you haven’t guessed, is you. Its owner and Creator is the great God of the universe - Jesus Christ. “For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: and he is before all things, and by him all things consist” (Colossians 1:16, 17). He has made us in the image of Himself, pledged to keep us alive and well, as long as we listen and follow His instructions. He assures us: “If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee” (Exodus 15:26).

It is so wonderful to study this physical body and learn its different abilities - each one teaching us wonderful lessons about our Creator and His law. “[God’s] law is written with His own finger upon every nerve, every muscle, every faculty, which has been entrusted to man. And every misuse of any part of our organism is a violation of that law.”1

Let us decide to learn more and more about how this body works and how we can take better care of this habitation. As we do this we will join with David and say: “I will praise thee, for I am fearfully and wonderfully made” (Psalm 139:14).

As the smallest item in this structure we care for, the cell is a very, very interesting unity, worthy of the first place in our study. The cell comes in many different forms and has unusual and complicated names for its parts and functions. It has been compared to a little city, complete with a police force, communications system, transportation company, energy production quarter, sanitation department, and restaurants.

To grow strong and remain healthy depend on the proper functioning of these cells. If something goes wrong, you get sickness and disease. And in order for the cells to work properly, you need to get the proper materials to it and get the waste away from it. This depends on perfect circulation. Thus the statement: “Perfect health depends on perfect circulation.”2

We need to invest time in further study about what materials are needed, how to keep the guards awake so they can keep out invading viruses, and bacteria, and poisons, and how this most wonderful machine can work the best and thus glorify its Creator.
