“For grace to be grace it must be free.” Dr. James White. God could have saved everyone and He is just. He could have left the whole human race in their fallen state and still be just. Him saving those He elected still makes Him just. God is just, period. This fallen notion of fairness is an insult, and affront to His character.
Dr. White is incorrect or incomplete. Grace is not unmerited favor but neither is it merited. There is something besides earning and completely free. This is the mistake he is making. Grace in the dealings of God with men is always granted for reasons. These reasons are not earning but neither is the grace of God given arbitrarily.
Noah found favor (grace) with God because he was a "preacher of rightesouness" in his Generation. This did not EARN favor or grace but neither was the man simply lucky. So the statment that grace needs to be free or it is not grace is very misleading as though a man just gets lucky.
In more than one place it says "God opposes the proud but gives grace to the humble. The humble are not lucky but neither is being humble or humbling yourself earning His favor. Nevertheless if a man is proud and responds in pride not only will God NOT grant him/her grace but God opposes them. Not a good place to be.
Now as to the idea that because God did something for some and let the others go to hell for no reason and that is still just because his idea of justice is different than ours, I have a comparison.
Is justice an entirely different matter with God? This seems to be an argument for the Calvinist position. It runs something like this if it were to occur in human father son relationships. This is what they think God says to us regarding his justice but let’s put it into a human family for clarity. The Scene is a discussion or lecture as it were, between a 9 year old boy and his father.
“So you, in you puny nine year old mind think that I am unjust because I belted you when you did the same thing your brother did and I did not belt him. Who are you to understand my justice!!!!?????? (We can see him getting red in the face.) Just because he does the same thing you do and is never punished does not mean I am unjust at all. I am always just. Always!! What you know of justice is nothing!! Just because I punished you for the same infraction and not him does not make me unjust. It means he has found grace and mercy in my sight, something neither of you deserved! So do not dare to think that you understand justice better than I do. You are not even 10 years old and I am vastly older than you. Whatever I do is just and when one of you finds mercy in my sight, well, that is more than just. What you both deserve is punishment, but I graciously extend unmerited mercy to him. It is completely just because both of you deserve punishment. Its just that He found grace and you didn’t. That does not make me unjust!!!!”
If the people who propose this were to experience this on the Job I am very sure they would not say their Boss is just for arbitrarily rewarding one and punishing them for no perceivable reason. They would cry, "unjust" very loudly.
