Abstract
The topic "Obstacles and Opportunities in Science for Christian Witness" is overwhelming, to say the least, so to keep the scope manageable, I should state at the outset that there will not be much discussion of apologetics as such in this paper. Instead, I will focus on the venues for witnessing themselves, the new opportunities that recent events have created, for example, in areas of the world formerly closed to Christian witness. We also need go no further than our own scientific institutions, where optimism and confidence are giving way to disillusionment, especially among younger researchers.
