The way Paul explains this love-hate concept shows God displayed His "hatred" before either Esau or Jacob had ever done a thing, and that His choice of Jacob expressed His love.
No clearer illustration shows that works had nothing to do with God's choice of whom He would use for His purpose. God simply exercised His sovereign right as Creator God to do completely and totally according to His will. He decided to love one and not the other. What about the progeny of Esau, the Edomites? Who are they today, where do they live, and what is their history? God indeed blessed Esau, as Genesis 27:39-40 delineate:
Then Isaac his father answered and said to him: "Behold, your dwelling shall be of the fatness of the earth, and of the dew of heaven from above. By your sword you shall live, and you shall serve your brother; and it shall come to pass, when you become restless, that you shall break his yoke from your neck."
Compare these blessings, however, with what God gave Jacob, or Israel. Who has God blessed superabundantly? Who lives in the fairest lands in all the earth? Who has been blessed with God's Word?
Did He do this because the progeny of Jacob is any better than Esau's or anyone else's? No, He did it because He is God. He exercised His sovereignty in our behalf. He loved our fathers and He loves us. Notice Deuteronomy 7:7-8:
The LORD did not set His love on you nor choose you because you were more in number than any other people, for you were the least of all peoples; but because the LORD loves you, and because He would keep the oath which He swore to your fathers, the LORD has brought you out with a mighty hand, and redeemed you from the house of bondage, from the hand of Pharaoh king of Egypt.
There it is, right in His Word. He seems to delight in choosing to pour out spiritual blessing upon those least esteemed and considered the weak (I Corinthians 1:26-31). Does this offend us, that He chooses one and not another? Are we disturbed that He distributes His blessings unequally, to one more, to another less?
