From the Lord’s revelation to Moses in Genesis 33:19, we find that God has the authority to have mercy on a certain person and to continue in his mercy, whether this person has sinned or not. Therefore, the selection of God does not depend on the works of man, but only on the mercy of the Almighty; and the salvation of man means his justification without merit, because of the limitless grace of God.we also read in the same sense in Exodus 9:16 that the holy Lord said to Pharaoh, the mediator, who was filled with the spirits of Egypt: “But indeed for this purpose I have raised you up, that I may show My power in you, and that My name may be declared in all the earth”. This divine declaration inspired Paul to write: “Therefore He has mercy on whom He wills, and whom He wills He hardens” (Romans 9:18).This is right because of the holiness of God. However, God is not a dictator, but he desires all men to be saved and to come to the knowledge of the truth (Romans 11:32; 1 Timothy 2:4; 2 Peter 3:9). If someone has opened his heart to spirits opposite to God, or has descended from a family, a clan, or people filled with thoughts contrary to Jesus, it is understood that God allows a harmful leader to oppose his orders openly, but God can also prove his eternal power with respect to such great a denier.In reply to the aforementioned verse of Paul’s epistle, some say that Islam adopts the idea that God misguides whom he wills, and guides whom he wills, for God, according to his holiness, has the right to mislead all men, since none is righteous. Yet, God does not behave in this manner, as other religions say, for he has mercy on everyone, and whoever accepts Christ participates in his own choice, for Christ is the only one who never sinned.But he who binds himself to the devil, the father of all lies, and loves money more than God, must not be astonished if the Holy One allows him to fall completely, and be unable to understand the word of God, as Jesus says in his gospel according to the evangelist John (8:43-45). God is free in making this decision, but man partakes in the responsibility, depending on whether he has repented sincerely or not.To clarify this point to the reader, we indicate that Paul sent these reflections not to the Gentiles, but to the Jews in Rome, to overcome the hardening of their hearts. He clarified to them that God would misguide them, though he had chosen them, if they did not open their hearts to his guidance in the gospel of Christ. This epistle of Paul does not present a philosophy to everyone, but it shows us how he treats the hardheartedness of the Jews.
