I don't know if you are asking me or not, but we must all be very, very careful not to overstep our bounds in areas of judging, and judgement.
I think that the righteousness that is being talked about there is some of the things I have just been talking about, and is also about the Spirit of the Law vs the letter of it, because the bar is raised even higher in the NT.
You also need to consider "when" also? In a person's individual life, etc? Does this mean just by the end of it for example? Or what about the ups and downs, or successes and failures, or keeping them pretty well at times, but then maybe backsliding, or losing ground, or falling back for a bit, to only maybe later on, then maybe picking it back up and doing a lot better with it again?
Again, way, way too many factors in an individual life, and I'm not going to exceed my purvue, or my pay grade, etc, because again, "I'm not God", etc.
God Bless.
