A description which tallies with Jurgen Moltmann’s writing of the world as a system open to the creative energies of God (see God, Humanity and the Cosmos, pp218-20). In earlier writing Peacocke used the image of the cosmos as a developing child in the womb of its mother (in Creation and the World of Science, Oxford: Oxford UniversityPress,1979) p142). As he would be very well aware, this analogy is strictly limited - foetusses and mothers are after all composed of exactly the same material. Another favourite analogy of Peacocke’s is that of God as an improvisatory composer, like J.S.Bach generating his fugues (Theology for a Scientific Age, London: SCM Press, expanded edn, 1993) pp174-75).
