Yes but not always all of our sin. Sometimes it takes a while to figure all that out. Paul mentions that the people of Corinth couldn’t recognize some sin and demands they throw out a member for it.
The sin of pride could probably doom us all.
You are right ... I think that the Holy Spirit reveals our sin to us as we grow in Christ.. but if people think they are "good enough" and that they "live better than their neighbor " they will never seek a Savior.. we need to really understand that we are sinners ...and we really do need a Savior..
It was pride that caused the fall of Satan and pride that cased Eve to eat that apple.. Personally I believe pride is the root of all sin ...
