Can you love a God like that? Brunner says, "NO!"

The doctrine of the double decree is, however, not only not supported by the evidence of Scripture, it is also impossible to equate it with the message of the Bible. It leads to an understanding of God and of man which is contrary to the idea of God and of man as given in revelation. It leads to consequences which are in absolute and direct opposition to the central statements of the Bible. Of course, the champions of the doctrine of Predestination have never admitted this, but, on the contrary, they have taken great pains to evade these conclusions, and to smooth out the contradiction; but this is speculative effort which, from their own standpoint, was inevitable, their argument becomes sophistical and contradictory. If God is the One who, before He created the world, conceived the plan of creating two kinds of human beings—non pari conditione creantur omnes, Calvin says explicitly—namely, those who are destined for eternal life—the minority—and the rest—the majority—for everlasting destruction, then it is impossible truly to worship this God as the God of love, even if this be commanded us a thousand times, and indeed at the cost of the loss of eternal salvation. Essentially, it is impossible to regard the will which conceives this double decree as the same will which is represented as Agape in the New Testament. All Calv1n’s arguments against these objections come to the same point in the end: these two conceptions must be kept together in thought, because both are stated in the Word of God. God is Love, that is the clear Biblical message; God has conceived the double decree, that is—according to Calvin’s erroneous opinion—equally clearly, the Biblical message; thus one must identify the God of the double decree with the God who is Love. But when we reveal the error in the second statement, the whole argument, which demands the impossible, falls to the ground. The Bible does not urge us to believe that the God whom it reveals to us as the God of love has created some human beings for eternal life and the rest for eternal doom. Equally inevitably the double decree contains a second consequence for the Idea of God which is in opposition to the Biblical message: God is then unmistakably “auctor peccati" [author of sin]. Zwingli drew this conclusion courageously, without “turning a hair”, only making the excuse that the moral standard which is valid for us cannot be applied to God. This at least can be said, and in itself the idea is not contradictory. Calvin, on the contrary, is terrified of this conclusion, and calls it blasphemous. In point of fact, it is impossible to say of the God whom the Biblical revelation shows us, that He is the Author of Evil. But Calvin tries in vain to eliminate this conclusion from his doctrine of predestination. Here, too, his argument simply ends in saying: “You must not draw this conclusion!”—an exhortation which cannot be obeyed by anyone who thinks.

The consequences of the doctrine of predestination are just as disastrous for the understanding of Man as they are for the Idea of God. Predestination in the sense of the “double decree” means unmistakably: All has been fixed from eternity. From all eternity, before he was created, each individual has been written down in the one Book or the other. Predestination in the sense of the double decree is the most ruthless determinism that can be imagined. 331–32 (emphasis original)

It's hard to know where to stop. I could post the whole chapter, it's so good. Do yourself a favor and read the whole thing: Chapter 23: The Problem of "Double Predestination," 321–39, The Christian Doctrine of God (the link is to a legal copy on Archive.org). There are also good used copies on Abe, or you could buy a new paperback from Wipf & Stock

By the way, the next chapter, an appendix on the history of predestination is very good too. As my seminary theology professor used to say, "You owe it to yourself to read it."

Let me just highlight this sentence, which sums up my feelings exactly: "it is impossible truly to worship this God as the God of love, even if this be commanded us a thousand times, and indeed at the cost of the loss of eternal salvation." Indeed!
