What do you mean when you encourage people to use their ‘spiritual imagination’?

This text is from a letter written by David Gooding in 2008.

You ask what I mean by encouraging people to use their 'spiritual imagination'. I do not mean, of course, to use the imagination to conjure up all kinds of things that are not in the text itself. I mean, rather, that it can be profitable to use one's imagination to visualize a situation that is described in the text.

For instance, when in Luke 7 our Lord raised the widow of Nain's son from the dead, the actual occurrence is told us in some detail. The young man was being carried out dead on his bier with his mother closely attending. She was a widow; the young man was her only son, and she was following the bier in the final stages of the process of death and burial. Our Lord stopped the process, and said, '"Young man, I say unto you, Arise." And he that was dead sat up.' It is helpful to visualize the scene: Where was the young man when he sat up? Well, on his bier of course; and then, surely, he found himself seated by the side of Christ.

We may dismiss that as an incidental, circumstantial detail; but in the experience of the young man himself, it was no mere detail that he should find himself seated by the side of Christ.

God's blessing be on you,
