If any important information relevant to plot, sub plot, character, or setting is revealed in the scene, it is relevant and not a filler. A “filler scene” is a scene that does not contribute anything to the story whatsoever.
I remember when people went to religion for truth, not comfort and good feelings. If I wanted comfort, I could get it in a pecan pie, among other things.
Faith is not dependent on Feelings.
“I didn’t go to religion to make me happy. I always knew a bottle of Port would do that. If you want a religion to make you feel really comfortable, I certainly don’t recommend Christianity.” –C. S. Lewis
