...it only seems rational...
Questions connected with the existence of God may be the most important that we can ask and try to answer. If God exists, then it is of the utmost importance that we come to know the fact; and it is also important to learn as much as we can about God and God’s plan. Implications follow that affect our understanding of the world and ourselves. If God exists, the world is not accidental, a product of mere chance and necessity, but a home that has been designed for rational and sentient beings, a place of personal purposefulness. We are not alone in our struggle for justice but are working together with one whose plan is to redeem the world from evil. Most importantly, if God exists then there is someone to whom we are ultimately responsive and to whom we owe our absolute devotion and worship. Other implications follow for our self-understanding, the way we ought to live our lives, and our prospects for continued life after death. On the other hand, it may be that a supreme, benevolent being does not exist. If there is no God, this too will affect our lives. We will have to look elsewhere for meaning and purpose; we will be forced to reconsider the grounds of what we take to be our moral obligations; we will enjoy or come to despair in the thought that we are entirely free from the obligation to live in devotion and submission to a cosmic authority figure. Whether there is a God or not will thus make a significant difference in the way we view the universe and in the way we live. And so it seems only rational to do everything we can to find out the truth of the matter.
