“When Lot and his wife were running from cursed Sodom to the mountains, to save their lives, it is said that his wife looked back from behind him, and she became a pillar of salt; and yet you see that neither her practice, nor the judgment of God that fell upon her for the same, would cause Lot to look behind him.
I have sometimes wondered at Lot in this particular; his wife looked behind her, and died immediately, but let what would become of her, Lot would not so much as look behind him to see her. We do not read that he did so much as once look where she was, or what was become of her; his heart was indeed upon his journey, and well it might: there was the mountain before him, and the fire and brimstone behind him; his life lay at stake and he had lost it if he had but looked behind him.
Do thou so run: and in thy race remember Lots wife, and remember her doom; and remember for what that doom did overtake her; and remember that God made her an example for all lazy runners, to the end of the world: and take heed thou fall not after the same example.”
– John Bunyan, The Heavenly Footman
