How To Stop The Enemy From Rejoicing

"It is the duty and interest of the people of God not to be afraid of evil tidings, not to be afraid of hearing bad news; and, when they do, not to be put into confusion by it and into an amazing expectation of worse and worse, but whatever happens, whatever threatens, to be able to say, with blessed Paul, None of these things move me, neither will I fear, though the earth be removed." (Matthew Henry)
