The U.S. Bureau of Chemistry and Soils calculated the chemical and mineral composition of the human body, which breaks down as follows:
65% Oxygen
18% Carbon
10% Hydrogen
3% Nitrogen
1.5% Calcium
1% Phosphorous
0.35% Potassium
0.25% Sulfur
0.15% Sodium
0.15% Chlorine
0.05% Magnesium
0.0004% Iron
0.00004% Iodine

Additionally, it was discovered that our bodies contain trace quantities of fluorine, silicon, manganese, zinc, copper, aluminum, and arsenic. Together, all of the above amounts to less than one dollar! That’s not very much, is it?!

In recent years, however, surgeons have used body parts from the deceased to perform helpful operations to repair or replace damaged organs, ligaments, veins, eyes, heart vales, tendons; to perform skin and bone grafts, etc. According to one report, 1.5 million tissue transplants take place in the U.S. each yr. Parts from recently deceased humans can be quite valuable in keeping the living in better health. But is meeting the physical needs all there is to caring for man?  Is man simply matter? Eventually we all die, and all Bible students come to learn that there is something of far greater value to us than our bodies – our eternal souls! 

Jesus posed two questions concerning our value: “For what profit is it to a man if he gains the whole world, and loses his own soul? Or what will a man give in exchange for his soul?" (Matt. 16:26)
Commenting on this verse, Albert Barnes noted:

       For what is a man profited ... - To gain the whole world means to possess it as our own - all its riches, its honors, and its pleasures.
     “To lose his own soul” means to be cast away, to be shut out from heaven, to be sent to hell. Two things are implied by Christ in these questions:

     1. That they who are striving to gain the world, and are unwilling to give it up for the sake of  [life in Christ], will lose their souls; and

     2. That if the soul is lost, nothing can be given in exchange for it, or that it can never afterward be saved. There is no redemption in hell.

To carry the idea further, Jesus willingly gave His life (John 10:11, 17-18) and shed His blood to redeem our souls from sin, death and hell (Cf. Matt. 26:28; I Pet. 1:18-19; Revelation 1:18.) The apostle John wrote that “He himself is the propitiation for our sins, and not for ours only but also for the whole world.” (I Jn. 2:2) How much are we worth to God? Everything Heaven could offer! - Roger Leonard
