Faith and reason are both intimately involved in searching for and finding the truth. We each grow up in some form of culture which shapes our perceptions and values. Through this culture we gain our understanding of the world and the human beings place within it. Our culture is made up of a community of like minded persons. I am one of them and through my interactions with others I work out my way of coping with the world and living.
But, an indispensable part of living involves the dimension of values and morality. Each culture has to deal with questions about the Divinity because, the answers to these questions shapes how a culture interprets the world and human existence. So, faith and reason are both necessary for each individual's life having meaning to the individual as well as the value of human life within any particular culture.
