Modern science discovered evolution not only of organisms but also of matter. From helium and hydrogen, the simplest elements, increasingly complex atoms were synthesized in the interior of stars. In supernova explosions the content of the stars became distributed into interstellar space. There, physical evolution continued with the emergence of increasingly complex molecules. On earth, self-replicating units evolved that crossed the threshold into life. There is no reasonable doubt that universal evolution is the result of a natural, probabilistic process that increases complexity from the original explosion of the Big-Bang to life, including human beings. The author of this book argues that Christianity can only make sense if nature is capable of freely becoming itself. Only in this way can creation bring forth human beings free to either accept, or reject, the loving relationship offered by the Creator. Therefore, the discovery of universal evolution by science only makes explicit what is already implied in the fundamental dogma of Christianity that God is love.
