Grade system or Caste system?

I’m best described in Joyful and sorrowful part of life but to all be it I’m always being thankful to God Almighty and it gonna take the grace of God to put everything’s in this world in place also the getting together of the light and the dark, Unlike getting together of the White and the Black, which means that the good God is gonna make the world a New Paradise for the entire Nation.....(In God We Trust)
