We have our own belief in life. I believe in God because since I was a kid my parents and all the people around me introduce that there is God to me. We often go to church every Sunday and we read bible a lot. I myself believe that there is God because the moment I pray each day to thank him for everything and free me from worries I know that he is listening. If you have God in your heart you will definitely surpass all problems that come your way no matter how little or big it is.
