In other words, since his chosen people are saved from Gods wrath and will therefore never experience this aspect of divine glory, God made the reprobates so that he can show off all that he is by damning them, punishing them, and torturing them in hell. This proceeds from his redemptive love. He does this precisely because he loves those he has chosen to receive his mercy. If I want to show my son how skillful I am with a rifle, I am not going to shoot him in the face with it. No, I will shoot a deer or a bear, whose life is dispensable. And I will do this because I love my son and want him to know more about me.
This is Gods love, and this love always wins, because God always wins. And this means that, because God is love, the reprobates those who are non-Christians and will remain non-Christians because of Gods foreordination can never escape hellfire. No matter how hard non-Christians strive to save themselves, God will catch them and send them to hell, where he will actively torture them with endless pain and anguish. Gods love (for himself, for his Son, and for his chosen people) guarantees the eternal damnation and suffering of all non-Christians. He will see to it that it happens.
