Romans Chapter 7 is a very serious and deep chapter. Unfortunately, many christian denominations do not understand this chapter. Apostle Paul clearly describes in this chapter the man in whom the law of sin and death reigns. Unfortunately, many christians today, living under the law of sin in death, not understanding it and not being freed from it, reassure themselves that Apostle Paul speaks of himself here, which means that everything must be okay and good with them.
But if we carefully study Scriptures, then we will see what Apostle Paul is really talking about here.
