Just a quick reminder that Romans chapter 7 is all about the law and how it affects people. Life under the law empowers sin and death. It is nothing to do with Christian behaviour, no matter how much people want to say that it is.
It is the condition and situation from which we are “saved”, so we could then enter into a spiritual relationship with God rather than one of slavery and fear.
“Wretched man that I am” is the situation in Romans chapter 7.
