Romans 9:15-18

Amplified Bible, Classic Edition

¹⁵ For He says to Moses, I will have mercy on whom I will have mercy and I will have compassion (pity) on whom I will have compassion.^(A)

¹⁶ So then [God’s gift] is not a question of human will and human effort, but of God’s mercy. [It depends not on one’s own willingness nor on his strenuous exertion as in running a race, but on God’s having mercy on him.]

¹⁷ For the Scripture says to Pharaoh, I have raised you up for this very purpose of displaying My power in [dealing with] you, so that My name may be proclaimed the whole world over.

¹⁸ So then He has mercy on whomever He wills (chooses) and He hardens (makes stubborn and unyielding the heart of) whomever He wills.
