He is fair. There may not be a level playing field by comparison, but God makes all things fair. Elijah did not realize that God had 7,000 on His side. Jonah knew about the mercy of God, but had not applied it to the people of Nineveh. Miriam didn't understand the meekness of Moses.
Meekness is strength submitted under authority.
Korah didn't understand the God worked through the authority of Moses and Aaron. David didn't understand the plan of God. He didn't see the big picture from God's perspective. John didn't understand the grace of God. Grace is a gift of God given to those who will receive it.
