Who receives God’s bless?

Through Genesis, we can see God’s bless only does not stay first son and stay second son or others. Where is standard of the God’s blessing? For example, in the case Cain and Abel, Isaac and Ismael, Esau and Jacob, Joseph and His brothers, we can see God’s blessing did not stay only on first son and stay second son or others. How do we take a decision? Does first son not take God’s blessing because of receiving bless in the world?
I think God’s bless does not stay because of not only first son but also second son and others. In the case Cain and Abel, God thought it is important who give right worship to God and how worship to God. Of course, they would receive education to Adam and Eve about God. If watch in Genesis 4: 6-7, God speak why he does not take Cain’s worship to us and through Hebrew 11:4, God explains the reason.

Also, the reason is same in the case of Isaac and Ismael. God promised to Abraham that Sara’s son would receive his inheritance. Nevertheless, Abraham distrusted God’s promise and he took Sara’s maid and then Ismael was born. He was sinned to God. Because of that, if we think another sense, Isaac is first son of Abraham.

Thirdly, in the case Esau and Jacob, before they were born in the world, God spoke to Rebecca that first son would serve second son. Because of that, Jacob could receive Isaac’s blessing pray. And also, when we watched Jacob’ sons, could know to be in the God’s good plan that Joseph could receive blessing of Jacob after Jacob was died.

Accordingly, God’s bless exist in his good plan and his predestination, not receiving God’s bless because of first son.

We must not forget God’s bless exist in his good plan and his predestination. God’s bless and selection is only in his will. Because of His will, we are saved. This is God’s love and grace.
