The way of the Lord is not just: People thought it was wrong for God to use Babylon to destroy Jerusalem. The Lord quickly corrected this idea (Ezekiel 33:18).
their way that is not just: The people's mistake was refusing to repent and accusing God of being unjust.
I will judge each of you according to his ways: The Lord's judgment is never random but matches their sins. If they repent, trust the Lord for salvation, and act justly and rightly, they have hope for the future (compare Ephesians 2:8–10).
