God does not exist. He is being-itself beyond essence and existence. Therefore to argue that God exists is to deny him.
Paul TillichFaith as ultimate concern is an act of the total personality. It happens in the center of the personal life and includes all its elements. Faith is the most centered act of the human mind. It is not a movement of a special section or a special function of man's total being. They all are united in the act of faith.
Paul TillichIn those who rest on their unshakable faith, pharisaism and fanaticism are the unmistakable symptoms of doubt which has been repressed. Doubt is not overcome by repression but by courage. Courage does not deny that there is doubt, but it takes the doubt into itself as an expression of its own finitude and affirms the content of an ultimate concern. Courage does not need the safety of an unquestionable conviction. It includes the risk without which no creative life is possible.
Paul TillichEvery person, every place and every action is qualified by this association with the unconditional; it penetrates every moment of daily life and sanctifies it: "The Universe is God's sanctuary. Every work day is a day of the Lord, every supper is a Lord's supper, every work a fulfillment of the divine task, every joy a joy in God. In all preliminary concerns, ultimate concern is present, consecrating them."
