Mind the gap. (James Emery White, pastor, author)

White is referring to the constant refrain at the “Tube” stations (London’s underground transport system). It’s a continual warning to stay clear of the gap between the station platform edge and the trains. It’s a good reminder to us to “mind the gap”—to stay clear of anything that would be harmful to our moral and ethical integrity.

Dear friends, I warn you . . . to keep away from worldly desires that wage war against your very souls. (1 Peter 2:11)
