“Parables sound absolutely ordinary; casual stories about soil and seeds,
meals and coins and sheep, bandits and victims, farmers and merchants.
And they are wholly secular; of his forty or so parables recorded in the
Gospels, only one has its setting in church and only a couple mention the
name God. As people heard Jesus tell these stories, they saw at once that
they weren’t about God, so there was nothing in them threatening their
own sovereignty. They relaxed their defenses. They walked away
perplexed, wondering what they meant, the stories lodged in their
imagination. And then, like a bomb, they would explode in their
unprotected hearts. An abyss opened up at their feet. He was talking
about God; they had been invaded” (Peterson, The Contemplative
Pastor, 32).
