"We see, therefore, that God created two groups of intelligent, moral creatures. Among the angels, many sinned, but God decided to redeem none of them. This was perfectly just for God to do, and no angel can ever complain that he has been treated unfairly by God.
Now among the other group of moral creatures, human beings, we also find that a large number (indeed all) have sinned and turned away from God. As with the angels that sinned: God could have let all of us go on our self-chosen path towards eternal condemnation. Had God decided to save no one out of the entire sinful human race, he would be perfectly just to do so, and no one could complain of unfairness on his part." --Wayne Grudem, Systematic Theology
