Romans 9:11-15, 18, 21

for though the twins were not yet born and had not done anything good or bad, so that God’s purpose according to His choice would stand, not because of works but because of Him who calls, it was said to her, “THE OLDER WILL SERVE THE YOUNGER.” Just as it is written, “JACOB I LOVED, BUT ESAU I HATED.” What shall we say then? There is no injustice with God, is there? May it never be! For He says to Moses, “I WILL HAVE MERCY ON WHOM I HAVE MERCY, AND I WILL HAVE COMPASSION ON WHOM I HAVE COMPASSION.”

So then He has mercy on whom He desires, and He hardens whom He desires.

Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use and another for common use?
