One of the big questions about God being sovereign is how He could allow or even create some people for judgment. Does God somehow take advantage of us, claiming to offer grace to everyone, while only giving that salvation to a few? How could a good God ever do something like that?

Fortunately the Bible itself comes preloaded with answers. Let me give 3 answers to this question:

1. Remember the human condition. The Bible is very clear on this. all humanity is dead in its sins, separated from God (Eph 2:1-3). We have all fallen short of God's glory through sin (Rom. 3:23). In other words, every human already deserves God's condemnation. The miracle, then, of God's sovereignty is that any of us are saved. But just as God can have mercy on some, He can also not have mercy on others, leaving them to His righteous judgment. God wills to leave someone under the power of their sin and selfishness, even to harden them against the gospel (Rom. 9:14-18). 

2. We are responsible agents. I wrote earlier that even if our actions are determined by God, it doesn't rob us of responsibility. God's predestination is not coercive. He's not holding a gun to the head of a reprobate forcing her to choose the wrong answer even though she desperately wants to choose the right one. She wants to reject God. Without His grace, sin still rules her will.

3. sufficiency vs. efficiency. As Christians, we have to affirm two statements, Everyone who calls on the name of the Lord will be saved (Rom. 10:13, Joel 2:32), and no one can come to Christ unless God draws Him (John 6:44, 65). That does not mean the death of Christ is incapable of paying for the sins of the whole world, it is certainly sufficient for that. But that payment is only effective for those that God draws. That's why we do offer the gospel to all people, not because all people will be saved, but because the people that God saves can come from anywhere.
