Let's say you are a good follower of your religion and you adhere to all teachings.?

If you are a good follower of whatever religion, can someone of another religion or outside of your realm put a curse on you? If someone tries to put a curse on you, will you be cursed?, or will your God not allow the curse to happen. Can you be a devout christian and have someone put an actual curse on you to a point where your religion does not work to overcome it.
