According to most biologists, immunity could possibly be one of the greatest gifts God has given to living things, including Humans. If any non-believer who is a biologist will doubt the power of God, they will never “comprise” immunity as something extraordinary that is so much beneficial to living things.
The immune system was most likely put into place in the original human body design. We know that God completed His work of creation in six days. Therefore, the human body and its functional parts, including the components of the immune system, must have been part of the original creation. God said that all He had made was very good (Genesis 1:31). Since there were no pathogens (germs), parasites, or diseases prior to the edenic fall and subsequent curse, the immune system may have functioned differently in that world unmarred by sin and death. The immune system serves more than just to “defend” against disease. The immune system was designed to interact with microbes and cleanse the body of aged, dying, dead red blood cells and bacteria even in the Pre-fall world. There are toll-like receptors in the immune system that have “sensory” function, as well as defense functions in animals and humans.
This is how most creation biologists view the immune system.
Immunology is the branch of biology that involves studying how the body is designed to protect itself from agents of disease called pathogens. The word immune comes from the Latin root word that means “freedom or protection from taxes or burdens.” This amazing system battles disease in a manner that is so complex and intricate that the most gifted imagination could not envision such incredible functions. In today’s world (post-Fall), the primary role of our immune system is to recognize pathogens and parasites, then to destroy them.
God is indeed a great artist and has given living things a fearfully and wonderfully made body by design.
But there is a problem!
Humans have altered/destroyed the normal functioning of their immune system and it is “killing” us and our generations.
If you have a very strong immune system, you may never need any drug because your antibodies (natural immunity) will fight for you.
