The sinful condition is forceful and strong. Genesis 6:5; 8:21 tells us that imperfect humans are mentally bent toward evil. Jeremiah 17:9 informs us that we have a treacherous unknowable heart (inner person), and the apostle Paul informs us that our natural desire is to do bad.
An improper desire (επιθυμια epithumia) can start in the corners of our mind. Dwelling upon or entertaining such desires normally intensifies the wrong desire, which, in turn, will influence the heart. Deep Bible study easily explained.
All of us have inherited a sinful nature, meaning that we are currently unable to live up to the mark of perfection in which we were created. In fact, Genesis 6:5 says we all suffer from, ‘our whole bent of thinking, which is nothing but evil.” Genesis 8:21 says that ‘our mind is evil from our very youth.’ Jeremiah 17:9 says that our hearts are treacherous and desperately sick.” Based on this alone, you must read this article.
