It is what they want. Some don't want it, but they sure deserve it.
Their punishment is owing to their sin. Mal 1:4, ESV
Whereas Edom saith, We are impoverished, but we will return and build the desolate places; thus saith the LORD of hosts, They shall build, but I will throw down; and they shall call them, The border of wickedness, and, The people against whom the LORD hath indignation for ever.
And your eyes shall see, and ye shall say, The LORD will be magnified from the border of Israel [Mal. 1:4–5].
"What God is saying to them is this: “My action and conduct with these nations which came from Esau and Jacob reveal that I loved Jacob and that I hated Esau.” After God judged Edom, they never made a comeback. When was the last time you saw an Edomite? They are just not doing business today. They went out of style years ago. God judged Edom, and this action of His looks like loving and hating. And God says to Israel, “I demonstrated that I loved you.” At the beginning, He never made that statement because He had to wait until it worked itself out. This reveals, therefore, that God’s choice is neither capricious nor arbitrary. God does not make choices like that. There has to be something to back it up. God had a real relationship with His people. He was the Father of the nation; He was their Lord, their God, and also their Judge. And he judged them most severely. In fact, it would seem that later on He judged Israel more severely than He judged Edom—but that was when Israel rejected the Messiah.
There is a great deal said today about “God is love.” It is an abstract statement to say that God is love. He says, “I have loved you and I have demonstrated it.” God was a long time telling the human family that He loved them, but He demonstrated it long before He said it. He demonstrated it from the very beginning—in the lives of Adam and Eve, from the time of the call of Abraham, and right down to the present." McGee, J. V. (1991).
