Physics in Theology

Richard Gaffin says this:

Since these two aspects of the believer's experience [i.e. resurrection in his own experience in the past and anticiplated future bodily resurrection] are integrally related to each other as well as to the past event of Jesus' resurrection, the unity involved may be expressed by saying that the resurrection of Jesus is refracted in the experience of the believer in a twofold fashion. (Resurrection and Redemption, P&R 2nd ed., 1987, p.60)

'Refracted'? I like how theologians use the language of physics to explain theological ideas. Gaffin seems particularly good at it.
