This article describes some of the basic elements of John Calvin's theology of creation and providence by situating them within a trinitarian framework. By using metaphors such as mirror, theatre and garment, Calvin pictured the earth as a generous gift of the Creator within which God shows his goodness, power and fatherly care. Calvin understands God not to be far away, but rather to be near and to sustain all life on earth by the power of the Holy Spirit. The visibility and tangibility of God's care as shown in the order of the universe and the reality of the world as a habitable place is of particular significance for Calvin. I argue that although contemporary science has changed our ideas regarding the universe in significant ways, there is an important aspect of Calvin's thinking that may be recognizable for the modern mind: the fragility of life on earth.
