Among the mass of fallen humanity, all guilty of sin before God and exposed to his justice, no one has any claim or entitlement to God’s mercy. - R.C. Sproul

“It still seems that if God gives grace to one person, in the interest of fairness he “ought” to give grace equally to another. It is precisely this “oughtness” that is foreign to the biblical concept of grace. Among the mass of fallen humanity, all guilty of sin before God and exposed to his justice, no one has any claim or entitlement to God’s mercy. If God chooses to grant mercy to some of that group, this does not require that he give it to all.”
