You're claiming that God loves humanity, yet your version of God keeps human beings conscious in hell for all eternity, for not believing in your Christian religion and dogmas. That's love? I'm pointing out the irony and inconsistencies in your assertions and beliefs.
Proof-texting. Cherry picking. In this case, hunting for elements in Judaism/Christianity and creating an entirely different story which lead to different and unintended conclusions. No, I am not just singling you out, but any person/denomination focusing on parts, not the whole.
The Old Testament is quite clear that the Jews will rule the world, and all of the nations will pay tribute to them or face divine judgment. That's expounded in the prophets, like Isaiah, Jeremiah, Zechariah..etc.
So much of the Old Testament centers on a way of life where all will see the wisdom of God and the joy and prosperity that emerges when living in this wisdom: Put God first; love and care for mankind. Beware of the desire for wealth and power, as this is selfishness, putting oneself first, and pampering oneself while others are in great need.
There are many Christians who believe Jesus only died for the elect, not all of humanity. Saying Jesus died for everyone and yet most people go to hell, doesn't say much about Jesus dying for anyone. If people have to convert to your Christian religion to be saved, from the wrath of your deity, that's not good news, that's bad news. There are hundreds of religions and philosophies in the world, many cultures and nations, that aren't Christian and people who are born into other religions, aren't interested in converting to yours. Yet your Christian version of God keeps people alive in a state of eternal torment just because they didn't accept your Christian religious doctrines and dogmas. That doesn't seem obscene and ridiculous to you.
Focusing on what "many Christians believe" is no better than focusing on what "many" atheists believe. These are red herrings that lead straight into fallacies. Fallacy is in the opposite direction of truth.
Why does Jesus or God have to die for anyone's sins? You say that as if it makes perfect sense, but for most non-Christians, that just sounds absurd. God, assuming he exists, has to die for everyone's sins, because supposedly he can't forgive people. God the perfect being, that lives in eternal, infinite, opulence and security, with perfectly manicured hands, never having to worry about getting sick or dying, much less being overpowered by anyone, is judging and condemning finite, mortal beings, who have to deal with all of the hazards, pain and suffering, poverty, fears, insecurities, diseases, and death, of earthly life. Has this deity that you grovel before, ever really experienced what it means to be truly human, like you and me?
Now let's look at the entire picture. Jesus turned his own small place and his own small amount of earthly time turning accepted beliefs upside down. He did this using Biblical teachings of his own people. Sins
are forgiven. Repentance (turning away from wrong-doing to right) is what is offered for the forgiveness of sins. The perfect sacrifice is a contrite heart. (This is all in the Old Testament, Hebrew scripture.)
Overtime, these Biblical teachings had been eclipsed by bringing sin offerings to the Temple for forgiveness. In a time of poverty, those in authority had found a way to milk even more from the poor. Jesus, of course, did it more humbly, but in essence, he marches up to Temple authorities saying,
You want a sin offering!? I'll be your sin offering! And in doing so, this will free the people of God from this,
your travesty, and remind them that just as a lamb paved the way for their freedom from bondage in Egypt and this will pave their way out of the bondage you placed upon them by using sin against them.
In short, God has no use for groveling.
Sin, repentance, a contrite heart is as normal for mankind as is climate change is for the earth. Yet, in both these instances, the powerful convinced the people if the people would just give them stuff (mostly money) they would make it all go away.
