Should man believe in God?

Man must believe, whether in the true God or in any false deity, which he might call god or something else. This deity could be a tree, a star in the sky, a woman, one's boss at work, a scientific theory, or it could even be some personal whim. However, he must have faith in something that he could follow and sanctify and refer to in his life course, and he might even die for its sake. This is what we call "worship", and worshiping the true God is what sets man free from being a slave to others and to the society.
