The third chapter of the Book of First John is quite plain concerning righteousness and wickedness. I do not understand why more has not been made of this chapter, since it shows clearly that the current preaching of lawless "grace" is a destructive error.
The reason why we now are able to see clearly what this chapter is saying may be that we are approaching the coming of the Kingdom of God to the earth. The Kingdom of God results in the doing of God's will in the earth as it is in Heaven. The Kingdom is not one of imputed, ascribed righteousness, but of actual righteousness of behavior. Perhaps that is why the third chapter of the Book of First John is being emphasized at this time.
