Faith is portrayed as more than a personal or weekly activity; it is meant to influence and positively impact the wider world. It is described as having a contagious effect, spreading through actions and examples that can inspire and transform communities and societies.

"Jesus used these images to illustrate his kingdom: a sprinkle of yeast causing the whole loaf to rise, a pinch of salt preserving a slab of meat, the smallest seed in the garden growing into a great tree in which birds of the air come to nest." These metaphors emphasize the subtle but powerful influence faith can have when actively practiced and shared, leading to growth and preservation in the world around us.
