I mean you are not saved just because of prayed the sinners' prayer once.This doesn't mean you can do whatever you want and you're still saved but how do you know you're really saved? This scares me. There are people saying when you're a christian and still like rock music then you're not saved cause you still love the world and when you love the world you're an enemy of God. This makes me feel like I can never be sure that I'm really saved and that God won't reject me and tell me he never knew me. How do you know you love the world? I mean do I have to hate the world and despise things like music or good food or something like this? ´ I mean when I feel like God might not even accept me then this is not really a good foundation.
