How do Christians who reject the idea of purgatory deal with the fact that most people don't repent of every sin before they die?

It is an observable fact that most people, even most Christians, don't repent of every sin individually before they die. Even that really great guy at church who's everyone's best friend and is first to let you know he messed up probably has been in a tiff or two where he thinks he was completely right and, in a lack of charity, or even with just a hint of pride, he refuses to see that he may have handled things improperly. For Catholics and Orthodox, with their theology of purgatory/tollhouses, as well as the Sacrament of Penance, this is a non-issue. That guy has all of those "venial" sins forgiven when he makes a good, honest confession of at least all his mortal sins. And, even if some venial sins slip through the cracks before death and aren't absolved, or aren't fully properly repented of, he will spend some time suffering in purgatory temporarily, and then will enter heaven for eternity thereafter. However, for Protestants who specifically reject both the doctrine of purgatory *and* make no distinction between mortal and venial sins (I'm thinking of those for whom the statement "stealing $1 and stealing $1 million are both damnable offenses" is generally a thought to be a true statement), it would seem that unless a man manages to truly and fully repent of every single little sin he has committed in his entire life, he would end up going straight to hell. Do Protestants who deny both of these tenets of Catholic faith simply bite that bullet, or do they have another way of working out this theological problem? ## Clarification I'm confused as to why I am getting lots of answers about earning our salvation. I am presuming that those answering believe, like I do, that people must repent of all of their sins in order to go to heaven. What I am asking is what Protestants think happens to people who neglect to repent of a single sin or maybe two or three, but otherwise live holy lives, when they die. I feel I must add this because I must have communicated something unclearly in the original body of the question.
