"I do not believe there ever existed a Christian yet, who did not now and then doubt his interest in Jesus. I think, when a man says, “I never doubt,” it is quite time for us to doubt him; it is quite time for us to begin to say, “Ah, poor soul, I am afraid you are not on the road at all, for if you were, you would see so many thing in yourself, and so much glory in Christ more than you deserve, that you would be so much ashamed of yourself, as even to say, ‘It is too good to be true.’”

– Charles Spurgeon
