31 For if we would judge ourselves, we should not be judged.

Judge yourself and confess your sins to God and ask to be forgiven.

30 For this cause many are weak and sickly among you, and many sleep.

These guys never judged themselves so the Lord judged them, and a lot worse things happened to them then if they would have just judged themselves. They became weak, sick, or died.

At the church I go to, we bow our heads before we start, and we give people time to fess up to the Lord if they haven't been doing it regularly (which every Christian should).
