THAT'S NOT FAIR
My grandson protested to his mother "IT’S NOT FAIR!" Of course he doesn’t know what "fair" is yet, but saying "It’s not fair!" somehow gives him a reaction and some leverage.
Not with God however. We may be very unfair on this earth that we rob of justice, but we can’t accuse God of being unfair. He’s done everything possible to enable us to make choices that will make a difference on the earth, and so many still reject Him.
