“There is no proof great enough to prevent doubt. Ir you base your belief on proof, sooner or later you will sink!”
“The more you believe, the more you doubt. The more you doubt, the more you ask questions. Knowing that questions left unanswered is the best proof for your belief.”
“Faith isn't absence of doubt. It's belief without proof, not without question.”
“Your enemies have neither the proof nor the backbone to stand against you, but say something often enough in vulnerable ears and incredulity turns to belief.”
“Christians rejected the need for proof to support belief in God, yet dismissed proof altogether when it was there.”
“I don't know. A proof is a proof. What kind of a proof? It's a proof. A proof is a proof, and when you have a good proof, it's because it's proven.”
