Where there is love and true justice, peace comes easy.
Think about the person you love the most in the whole world (maybe that is yourself). THAT is love, and everyone should be treated as if they ARE that favorite person. Does that seem not enough? Then treat everyone as if they are God.
As far as justice is concerned….good luck getting THAT in life! But after life, justice is absolute…AB-SO-fricking-LUTE!! It’s, also, PERFECT. Explain perfect? Whatever a person does to another person, they may as well be doing it to themselves! The rolls are reversed, where there is perfect justice. Example? I scream at you, “You are so stupid, and I can prove it!” Well, I just signed up to be screamed at, probably for eternity, and, all the while, during that time, realizing just exactly how stupid I truly was to have gotten myself here/there, by treating someone else so lousy!! Perfect Justice.
So……you want peace, treat “yourself” (everyone!) well!
