Precision-crafted

God engineered the human body so our 206 bones, the heaviest part of us, make up only one-fifth of our weight. Yet bones are strong enough to protect and support every other cell, bearing the compression and tension we exert through ordinary activities such as walking and lifting heavy items.
By comparison, wood snaps at such impact. And steel, strong enough to bear such force, weighs three times what bone does and would hinder our movements. No other matter strikes such a perfect balance between strength and weight.
Furthermore, our bones are hollow — a big part of what reduces their weight — and the interior efficiently produces a trillion red blood cells each day.
With the psalmist, we can proclaim to God, “I praise you, for I am fearfully and wonderfully made” (Psalm 139:14, NRSV).
