All sickness is a by-product of man s original sin. But all sickness, when incurred is not always a result of a particular sin. For this cause many are weak and sickly among you, and many sleep. There is a natural occurring of disease caused by either sinful habits or sinful lifestyles. Cirrhosis of the liver is often caused by alcohol consumption, whereas hardening of the arteries result from gluttony.
Smoking can cause lung and vascular problems leading to sickness and death.
There are also sexually transmitted diseases such as AIDS and different forms of venereal diseases that are the results of sinful lifestyles. Also to be considered, there are many sickly, dying saints who have not been guilty of a particular sin or a sinful lifestyle. They have simply been called on to minister through their own personal suffering. This study is not to judge every sickness to determine for what purpose it is. Only God can ultimately do that.
