Sanctification and Fornication
Not just fornication but a whole lot more. Personally — without consulting the Bible — sins take its toll, whether spiritually or physically. The Almighty Father punishes by allowing those rebel spirits to cause pains debilitating maladies,and all sort of illnesses and conditions.
And so it is safe to say that tracing all iniquities that have brought the present state, should be addressed sooner than later. Because somehow God can be an avenger Lord against these things. If He is annoyed, be ready to whatever comes at hand.
In 1 Thessalonians, chapter four (4), one should live a life that ia pleasing to the Eternaml God. That is, to avoid fornication for the sake of sanctification.
It is a must to be able to control the body in holiness and honour, not for lustful passions.
The Almighty God is not calling us to impurity but in holiness.
