I believe Jesus was simply a man. He died, but not "for our sins".
Jesus was a hero to outcasts. He gave outcasts of society a sense of dignity. They felt loved, accepted and appreciated by God because Jesus was a man of God. Society put Jesus on the cross, but it wasn't defeat for the outcasts. It was, instead, the opposite. Society unjustly persecuted an innocent man, a good man who restored the dignity that outcasts of society lost because of what they meant to society. Unfortunately, society couldn't accept that man either. That man willingly allowed himself to be arrested, charged and condemned for those for whom he cared.
Because he was a man of God, it was a sign of support from God. Society was the oppressor. Jesus was their ally, their supporter. Society had made them feel worthless, but here was a sign God didn't care what society thought of them. God accepted them despite what society thought. That is what I consider to be the significance of Jesus.
Forgiving sins? The question is whose "sins"?
Should rich and powerful people, people with power and money receive the same support as the outcasts whom Jesus supported? I think it would be to a lesser extent.
With power comes responsibility. Very often, power corrupts.
I think some people have the wrong concept of the crucifixion.
It wasn't for everybody. It wasn't for rich and powerful people. It was for poor, downtrodden, oppressed and persecuted people. It was for people with low self-esteem, stripped of their dignity, humiliated.
A CEO with a salary of $1 million may think of himself as a Christian and chant slogans like, "Jesus saved me," but if he lives like a king and doesn't help the poor, persecuted, oppressed and outcasts of his society, doesn't live like a "little Christ," like Jesus, I have to say that the crucifixion means very little to him. Moreover, it's a sign that he doesn't understand the crucifixion.
If you've got money, you've got the power to help the "little people," but if you don't help the little people, you are nothing, no matter how much you earn.
The "sins" of the "little people" are acceptable to God because they are fairly insignificant. Jesus didn't die for "big people." He died for "little people."
A "big person" (ie. a rich and powerful guy, including religious leaders) who causes injustice and misery in society must become one of the "little people" to be accepted by God. His "big person" status isn't acceptable because of his misuse and abuse of power.
Justice and redemption can't happen without some humiliation.
Whose sins? It's a matter of social status and social standing. Are you one of the little people? That's the question.
To be honest, I don't live like one of the "little people." I just aspire to live like one.
