For starters, this is a seriously meant topic, and I really would appreciate any or all answers seriously trying to explain these things to me. For those of you who do not like Chrisitanity, please hold you fire while I try to get some aswers, ok? ;-)

Though living in a country where Christianity is supposedly the state religion I have never understood Christianity very well, and as few people in DK are actually religious, I have never gotten any the wiser.

Now, at Easter, I wonder again.

Jesus died on the cross to appease God, because humans were sinful - is that true?

Q: how could a blood sacrifice solve that?
Q: how could God create a son and sacrifice him, and that appeased his anger??
Q: if people just keep on being sinful, what is achieved?

Q: if Jesus died for our sins, does this mean that we can go on sinning?

I see the person Jesus as a great teacher, who had a lot to give. But I do not understand this other part of it.
