Here is a pretty good metaphor from a graduation speech by President Chuck Kelley at the New Orleans Baptist Theological Seminary :
“As we are seeing all these reasons for despair and discouragement and all this sense of panic and fear that is sobering men at every level of our society, there is one thing we know as believers: That as ministers of the Gospel of Jesus Christ, we own the night.”
“Owning the night” is part of American military parlance. One of the major reasons, Kelley said, that the American forces are among the most effective in the history of the world is night-vision capability, the ability to fight and win in the midst of darkness.
“They have done this not by eliminating night, but by subduing it, by discovering that even in the night, there is a light that allows you to see,” Kelley said. “What is true on the battlefields of the world is of far greater significance in our lives and for your purpose.”
