Antje Jackelén's book Time and Eternity is a thorough and carefully presented theology of time and, by its very essence, an incomplete and open thought model because time will always be dynamic and relational. This approach is an excellent example for the dialogue between science and religion because it uses resources not tapped in the dialogue so far: hymn-books stemming from Germany, Sweden, and the English-speaking world published between 1975 and 1995. They are taken as resources for a critical investigation (...) on the meaning and importance of the notion of eternity for the interdisciplinary dialogue, which is characterized not as a synthesis but as holding a beneficial tension, or "eutonia." I suggest that this approach can be taken even further by merging it with a model of time developed by the German mathematician A. M. Klaus Müller: The crossing over of time modes in a relational matrix of time also gives clear insights into the time of God not only as futurum —time as extrapolation of the past and present—but also as adventus —time which is to come.
