1. God's choice of Jacob over Esau was
according to God's purpose of election.
Again in Rom. 11:5, 6 we are told that God's choosing of a people is not based on works as follows: "Even so then at this present time also there is a remnant according to the election of grace. And if by grace, then it is no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work." Thus we are told that God's choice of a people is by grace and not works. Furthermore, we see the impossibility of mixing grace and work in this choice. It is not part grace and part work. It is either all grace or all works and he tells us plainly that it is all grace.
Now grace is defined as the "unmerited favor of God." Thus those chosen have done nothing to merit God's choosing them!
Finally we are told in Rom. 9:14 16 that God's choice of a people is not based on man's will (choice) or man's efforts: "What shall we say then? Is there unrighteousness with God? God forbid. For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him that willeth nor of him that runneth, but of God that sheweth mercy."
From this passage we draw the following
In conclusion, God's choice of a people is by grace (unmerited favor) alone. God was under no obligation to choose any one, but he did and we should be extremely thankful that he did.
