How religion helps society
Many people tend to go too far with their beliefs. They ignore the main rule: be humble and kind to other people, regardless of who and what they are. But how can you know where you should stop? It's simple - follow your heart. It is hard to realize what your heart is telling you and what is right and what is wrong, but once you realize that everyone's good needs to be put on the first place you will also realize what you have to do.
There is no such thing as a life that you live through rules. We have needs and God gave them to us to see how we will handle them. He didn't gave them to us to see how we repress or overuse them. So you need to open your heart to God's Words. That is not easy, as well, but it helps that there are many ways to do that. Almost every religion has their holy book or books that carry the message of God. So you can read it and make a conclusion for yourself. You don't need a priest to tell you that, but he can help.
Once you realize these things by your own, your belief will become much stronger. Religion will help you deal with things in life you don't know the reason why they happen or their ending and it will help you answer the questions you don't know the answer to. It helped me and I am sure it will help you as well. Real Christians, as every other good people, will help you find your path and help you also go through any other hard period of your life.
I hope this helped you and that you will find your own answers and ways to enjoy the things God gave us.
