Medicine approaches the patient at many different levels.
An internist will take a history and perform a physical exam. A radiologist can procure an image of a disease and analyze it with varying radiation and magnetic frequencies. A surgeon may hold a diseased organ in his hands and attempt to repair it or remove it. But only under the microscope, can one truly understand the intricacies of the disease. At the microscopic level, the disease process is laid bare. We can observe how a disease can wreak havoc on the body, how it can spread to other organs, and how the body attempts to fight off the disease with its immune system. As sophisticated as we may be in describing and understanding what is happening, there is a gap. We may able to describe what is happening, but can we truly understand why?
As you do not know what is the way of the wind, or how the bones grow in the womb of her who is with child, so you do not know the works of God who makes everything.
The more one understands the biology of life and medicine, the more mysterious it becomes. And is it any wonder? God created it and designed all life to give glory to Him.
For we walk by faith, not by sight.
2 Corinthians 5:7
Our faith is trusting in the God who created life, not trusting in the mechanisms of life.
