So the myth of the Fall is a myth of man's potential greatness. Since we are free, we are called upon to be the creator of new values. We are free in that we are able to cooperate voluntarily with God, to produce new values. We are destined to be created creators. Our creative activity should bring us into a dynamic experience of eternity.
Man thinks of the paradise that was and the paradise to come.
Hence the Bible combines the myth of the golden age in the past and the messianic hope of a millennial age in the future. Following the path of tragedy and heroism, man travels from the original Eden, in which freedom is unknown, to a paradise in which there is a knowledge of freedom. Paradise will be reached through human creativeness. Thus, the Christian revelation is first and foremost a message of the kingdom of God, the end of time, a new heaven and a new earth. Tillich understands the Fall story as a mythical description of the transition from essential to existential being.
