"My position concerning God is that of an agnostic. I am convinced that a vivid consciousness of the primary importance of moral principles for the betterment and ennoblement of life does not need the idea of a law-giver, especially of a law-giver who works on the basis of reward and punishment"
Religion is a way of thinking, a way of believing, and a way of redemption.
In one perspective, there is a God that is real, he is everywhere, and he does everything with a flick of his finger. He is an actual person, he can bring the dead back if he wanted to, and he created the world. In another perspective, God is merely a figure that symbolizes what we as humans should be. He does not truly exist, but we use his example to show us the perfect person.
Most religions have the same basic principals and foundations; that we should not murder, we should do kind to one another, we should respect those with power over us, etc. Each religion has their own way of practicing those basic principles, but whichever you are born into is what you will most likely follow throughout your life.
For everything in this world, there is an opposite. Light, dark; up, down; freedom, slavery; on, off; faith, detachment; Hate, Love. You are not required to have absolute faith in God, but each religion emphasizes the practice of faith in order to keep ourselves from being detached from society and keep our minds focused on Love, and not Hatred. Most people know the typical lifestyle that makes up what is "good," and "bad," but religion is just a way to reinforce that within our lives with a symbolic person, like God.
