I've got a little slogan that I say it quite a bit; it might be good for you to take it. "A winner never quits, and a quitter never wins." Just think of it: "A winner never quits, and a quitter can't win." You must hold on. And before you even start, be dead sure you're right. And then be persistent. Let nothing move you. Go on. I've had quite a bit of experience of that, and you know it. But I know this one thing; when you're dead sure that you're in the will of God, when you're dead sure you're centered in Calvary, nothing's going to move you. You're there.
William Branham, Sermon "Perseverance"
