Was Jesus REALLY that great of a guy? I mean, he did say he did not intend to bring peace to earth, but a sword. And he did refer to one non-Jew (Gentile) woman as a "dog" when she asked for him to heal her daughter. Matthew 15:22-28. He basically said, in whole, "No, I will not help you, because I came to help the Jews, not the non-Jews." Then, with all of his power, he was ultimately convinced to change his mind by her basically saying, "even the dogs eat the crumbs that fall from their master's table".
Jesus also gives numerous examples of bad advice (not saving money, not planning for the future, make people want to persecute you, if someone hits you, invite them to do it again, etc) and examples of things that are just patently absurd (marrying a divorced women is adultery, don't have sexual urges, if your eyes or hands do something wrong, pluck it out/cut it off, etc). And thought crimes, as you gave examples of, are also absurd. Thinking about doing ANYTHING immoral or harmful is NOT as bad as doing it. It actually is good if you can THINK of doing something like murder and have the restraint NOT to. To say "thinking it is as bad as doing it" sort of permits bad behavior since you haven't drawn a distinction between the two.
So, on top of his "sacrifice" not really being a real sacrifice, he's also a bit of a dick and a bit crazy. Do we REALLY need to strive to be like that character?
Speaking on the bit about the woman being called a dog, it was figurative language. In fact, Jesus said it in a way that He referred to the gentile people as household pets and Israel were the children. (Hence the woman's reference about them eating the crumbs that fall from the table. In fact if we know anything, even back in that time, it's more likely the children would feed their pets big chunks of food from their plate) It wasn't meant as something to be taken offense to. Of course the sword Jesus mentions that He's bringing, is simply His message. Those who accept it, will be at conflict with those who reject it. It's not like Jesus was saying He's come to kill as many people as possible. Not that kind of sword.
So sayings like cutting off your hand and plucking out your eye. Those things were meant to cause you to gasp. The first thing is, if Jesus really was telling people to do that, how come Peter still had his hands and eyes everytime he messed up? How come all the disciples kept their body parts? So, we can conclude Jesus didn't want people to do that. If that's so, what was His angle? It was again that the commandments were meant to be kept perfectly. That even if any part of your body caused you to break them or tresspass against God, it would be better to cut them off and enter God's kingdom maimed. So the angle was to get people to come to the end of themselves, that they can't keep the commandments. It's the same with the thought crimes. By the way, it's not just the thought, but for instance "to look" after a woman "to lust" for her, you commit adultery in the heart. So these thought crimes are essentially yeilding and fantasizing in a way, not just a passing thought. (Passing thoughts could come from anywhere. Particulary by suggestion) Yet who hasn't fantasized concerning sex? Who hasn't hated someone with an intense passion? We call it human nature, but Jesus says these things to show us it's a corrupt nature.
On other things Jesus said, such as turning the other cheek (literally and figuratively), He's teaching that when someone offends you, give them grace. So it is that God will give us grace, when we offend Him. That of course, was before Jesus went to the cross. Now we give people grace, because God has given us grace. This is the christian teaching.
You mentioned something about not saving money and planning for the future. I assume you are referring to Jesus telling the disciples to follow Him, and them leaving behind everything right there and following Him. Also might be referring to the rich young ruler, who Jesus told to sell his belongings and give the proceeds to the poor.
Firstly, Jesus never told people not to plan for the future nor don't save money. He told them not to worry about what they are going to eat or what they are going to wear. He said to first seek the kingdom of God and the righteousness of it, and all those things would be added to them. So ultimately, the things we need, was in doing the work of the kingdom. Whatever we need. In fact, I have many invention ideas that have been inspired by the faith. For instance, we know this country is in a lot of debt, but I always say one invention could change all that. Say something that would make energy use more efficient, we could sell that invention to other nations, and cause great profit for the nation to come in. I feel like I have an idea for such an invention because of what I've learned from my studies of my faith. So if I'm successful in that endeavor, it would be an example of what Jesus was talking about. If anything, Jesus tells us to be good stewarts. Just look at the parables concerning the talents and all that. The master in that parable was mad because one of his servants couldn't have at least put his money in the bank, so he could get some interest on that thing! So for christians, we are just in a different kind of business, and our needs will be taken care of.
Secondly, the disciples did leave everything behind to follow Jesus, but they didn't lose anything. I guess in Matthew's case, he did leave his job, but that job was full of crook activity anyway back in those days. (Of course we still hate tax collectors, only now we call them bill collectors.) They left all that behind, and became family themselves. Of course I would say they were more free back then, at least in their thinking. Concerning the rich young ruler and what Jesus said to him, that was a little bit different situation. It will take me a little bit to explain, once again going into the thing about Torah and grace. Yet all in all concerning the command to sell everything and give the proceeds to the poor, Jesus only told that to the rich young ruler. No where else, did Jesus tell that to anybody. Yet again, this situation is a little bit different than with the disciples. (Not that there is nothing wrong with selling your belongings and giving to the poor.)
Allow me to get on topic a bit, though. Other posters have covered the big issues with this thread topic. You simply can't draw a universal Christianity premise here. Defining which god it is that we're talking about IS important. So, your intention is right, but your execution leaves something to be desired. The best you can do with this is define what god is TO YOU and argue that point (which, essentially, you have done). Just don't assume that these are things that are/should be universal (your Genesis as literal truth, for example).
Arguing against your point, it's really simple to debunk the bible as a collection of stories written by men in the Bronze Age.
First line of the bible. A claim is made there. Prove that claim. If you cannot or if you do not desire to, there is no need to have the conversation. EVERYTHING in the bible hinges on whether or not that claim is true.
I guess what I really want to show is things that are universal, things that you can't leave out, in determing true Christianity. Discussing those tenets that I listed
