===Imperfection of sanctification in believers===
That is a similar matter. In the Larger Catechism, it is question 78 while assurance is dealt with by questions 80 and 81, nearby.
====Romans 7:7-25====
In Romans 7, the apostle considers the old testament law, the law which is holy and just and good—and comments that it stirs up sin. Does that apply to people who are saved?

:He [the apostle Paul] then sets before us an example in a regenerate man, in whom the remnants of the flesh are wholly contrary to the law of the Lord, while the spirit would gladly obey it.

:Some mock these things and imagine that Paul is here speaking not about his own person, not about the converted and holy, but about the ungodly. This sophistry must be rejected. David is speaking about himself and about all saints when he says [Ps. 143:2]: "In your sight no man living shall be justified," and when he says [Ps. 51:5]: "Behold, I was conceived in iniquity." Thus Paul is speaking about himself, and he includes all saints by his example. Since this interpretation of Paul has firm and clear testimonies in the Psalms, it is certain that foreign interpretations should not be invented.
