John 9:26

26. Said they… again Proceeding apparently to cross-question him, in order to detect some refutation of the miracle. This cross-questioning the man indignantly and sarcastically declines. He refers them to his explicit narrative in his former examination, which they endeavoured to slight; and he ironically imputes their zealous questioning to a desire to become his disciples. The keenness with which sceptics scrutinize the Gospel often surpasses the earnestness of its believing students. And it is a striking fact that critical attacks have stimulated Christian scholars to a profounder study of the word of God, and have thus resulted in a truer understanding of its depths of meaning, and clearer demonstrations of its infinite truth.
