No sin in a believer?
Hence may appear the extreme mischievousness of that seemingly innocent opinion: That there is no sin in a believer, that all sin is destroyed, root and branch, the moment a man is justified. By totally preventing that repentance, it quite blocks up the way to sanctification. There is no place for repentance in him who believes there is no sin either in his life or heart. Consequently there is no place for his being perfected in love, to which that repentance is indispensably necessary.

11. Hence may appear the extreme mischievousness of that seemingly innocent opinion, That “there is no sin in a believer; that all sin is destroyed, root and branch, the moment a man is justified.” By totally preventing that repentance, it quite blocks up the way to sanctification. There is no place for repentance, in him who believes there is no sin either in his life or heart. Consequently there is no place for his being perfected in love to which that repentance is indispensably necessary.
