help me understand this OT and NT stuff

[Sara0229]

I find reading about religions fascinating, not sure why cause I think they do more harm than good, but anyway I was reading passages from the OT that say you can't do all this stuff and talked about killing babies, stoning children, killing nonbelievers.....

So I was talking to a Lutheran about all of this and as the conversation went on I just became more and more confused. So if the NT trumps the OT then why is the OT in the bible? I mean why have all that in there if you don't have to abide by it? You just ignore it because you know killing babies is wrong? But God told you to do it and it's the word of God right? He told me he thought that the 10 commandments are very important but they're in the OT. So I guess one of the commandments says not to kill but then god tells you all these reasons that you should kill people in the same OT.

I'm so confused I just had to stop the conversation because it was making my brain hurt. I like to understand others points of views but I can make any sense out of all this.

Maybe someone can explain this to me better. What is the difference between the OT and NT as far as what you should follow and what you shouldn't?
