Yes that is right. God sent himself > to sacrifice himself > to himself > to save us all from himself.
There is of course some Old Testament stuff that leads up to this. The basics of that is: God created Adam and then he created a companion for Adam, Eve. They lived in a paradise called Eden. Inside that paradise, there was a tree of knowledge whose fruit they were not to eat. The devil was like "I can't believe God would be so dumb as to put the forbidden fruit right there in the Garden of Eden, that makes as much sense as storing your steaks right down there by the dog bowl." So the devil, seeing his opportunity, took the form of a serpent (Because who doesn't trust a snake?), and convinced Eve to eat the forbidden fruit - obviously women are easier to corrupt. Then Eve convinced Adam to eat it too. At this point they realized they were both naked. So they clothed themselves - probably in big leafs. God found out and he was royally pissed. So he threw Adam and Eve out of the Garden of Eden and told Eve that when she had kids it would really ****in hurt now. So then they went out and multiplied, and God did some sadistic things with some of their future family like when he almost made Abraham kill his son in front of him just for kicks, and then he got mad at society when they were trying to build a tower to heaven, so he gave them all different languages so they could not easily coordinate on such an endeavor in the future. God then really got pissed at humanity again so he sent down a great flood that flooded the whole world and all the animals were saved upon this great big wooden ship he had Noah build. Finally the floods receded and the ship ran aground somewhere up at the top of Mount Ararat. At this point it kind of sucked for penguins and kangaroos because they had a long ass walk ahead of them to back to their homes. God then got this dude Moses to lead his people out of slavery in Egypt and to the promised land. In the process he give them a bunch of rules, some pretty good ones like you shouldn't steal, others having to do with exactly how women should be treated as property and proper slave ownership. He also commanded them to commit wholesale genocide and even take and rape virgin little girls as spoils of war. So anyway, time just continues to go by, wars are fought, there are some good kings and not so good kings, some wise verses are added to the Bible and so on, and then finally, God sends himself to sacrifice himself to himself to save us all from himself because he was still really pissed about that whole deal with Adam and Eve eating from his prize fruit tree. However, its good that he did it being now we won't all burn in hell for all of eternity because of that. Of course, most people will still burn in hell because of that time he got pissed off about humans getting together and trying to build that tower to heaven and to keep it from happening again he split everyone up and gave them all different languages and cultures, so really, its mostly just white people of European descent and those that Europeans colonized and imposed their religion on that will have any hope of avoiding burning in hell for all of eternity, the rest of the world can just go to hell as far as the good Lord is concerned. That's just fine though, because all and all, God just likes whites of European descent more than anyone else. For example white people in America will pray for things like a parking space or to win a high school football game and the good Lord delivers. Meanwhile if a sub-Saharan African prays for her kids that are starving to death in front of her, well God just doesn't have time for that.
God gives us all a chance though. You can be dying a horrible death at a young age and if you beg God enough, he might, just might change his mind on that - but only if you really, really beg him and even then, no guarantees.
There you have it, Christianity in a nutshell.
