Paul lamented for his fellow Israelite in Romans 9. They were the privileged bunch with so much revelation from God and yet they miss the salvation of Christ. While many people are upset about God favoring some people, they miss the most important message of God. That is, with God, there is no difference and no favor, irrespective of races, honor or dishonor (in man's eyes). God loves and Christ died for all. The diversities are created by God and He has the right to put people into different groups. But God is no respecter of persons, he chooses to accept the rejects of men. The Israelite may have so much revelation of God but yet they fail to know God and His Son Jesus Christ. Salvation is a grace of God offered to all and it to be accepted by faith and not according to any social background or standing or even works of the laws. Get the correct understanding of God's love and think not God is unfair in creating diversities.There are many races in the world. Some people are born into the rich families whereas some are born into poor families. Unfairness is normally claimed by the ones in the 'unfortunate' states of poverty or sickness or rejected. Yet, we know that many that were born of the rich did not do well in life. Many just spent their lives away in wild livings, in drugs, in alcohol, in wild parities and suffer painful death in overdose or accidents. On the other hand, there are many successful, happy and rich people that started life as poor. So, is a good inheritance a blessings or a curse? The answer is obvious, it depends entirely on you. God has made sure of that. Everyone can, no one is excluded, from knowing and coming to receive God. Such is the message of Romans 9. The privileges of one race or status does not ensure one's salvation. The Israelite is a good example. They were so close to God and yet many miss His salvation through Jesus Christ.
While God has the right in Rom 9:18 to show mercy or harden, we need to see His character of love in Rom 9:22 patience for those deserving wrath, 9:25-26 calling those outcast His people.
How does God harden Pharaoh's heart? Not by creating Pharaoh's that way (because everyone is created in the Image of God and give free will) but by going against Pharaoh's selfish desire to keep his slaves.
Chapter 9 is in fact, a reinforcement of Chapter 8 God's love for you is much much more than any adversity or restrictions. We cannot use our race or culture or wealth or whatever as excuse to reject His love for us.
The full details are given in the mind-map below and I hope your mind may be enlightened and be willing to receive His love for you:
