Doubt discovers difficulties which it never solves; it creates hesitancy, despondency, despair. Its progress is the decay of comfort, the death of peace. "Believe!" is the word which speaks life into a man, but doubt nails down his coffin.
It is not my aim to introduce doubts and fears into your mind; no, but I do hope self-examination may help to drive them away. It is not security, but false security, which we would kill; not confidence, but false confidence, which we would overthrow; not peace, but false peace, which we would destroy.

It seems to me that doubt is worse than trial. I had sooner suffer any affliction than be left to question the gospel or my own interest in it.
Some of us who have preached the Word for years, and have been the means of working faith in others and of establishing them in the knowledge of the fundamental doctrines of the Bible, have nevertheless been the subjects of the most fearful and violent doubts as to the truth of the very gospel we have preached.
When the New Testament talks about doubt, whether you're talking about the gospels or the epistles, it primarily focuses on believers. That's very important. It's as if you have to believe something before you can doubt it; you have to be committed to it before you begin to question it.So doubt is held up as the unique problem of the believer.
