When a member of any religion is taught and believes that his or her belief is the only way, there can be nothing but conflict, hatred, and mistrust. I know that there are organized religions that do good deeds and there are members that are good people. What upsets me is when they think that they are better than others because they belong to a certain church, etc. Some of the most two-faced people I have met have been the most active in their churches. Interacting with God does not have to occur in a religious building on a certain day of the week.
Spirituality exists within our hearts.
It is how we treat other people, and how we live our lives in this world, not how often we attend church, that matters. If you doubt your faith in a higher power, just witness a birth, or take a walk outdoors. Write a gratitude journal each day and you will become aware of the good in your life. I don't feel that God had anything to do with the events of 9-11. Terrorists' believing that their religion was the only correct one was the cause.
