” Some people deny that they have an inner sense of God. But their awareness of God will often make itself evident in a time of personal crisis, when deep-seated convictions of the heart show themselves in outward words and deeds. Several years ago I was a passenger in a car with several friends, including a young woman who in conversation was firmly denying that she had any inner awareness of God’s existence. Shortly thereafter the car hit a patch of ice and spun around in a complete circle at high speed. Before the car came to rest in a large snow bank (with no serious damange) this same woman could be heard distinctly calling out, ‘Lord Jesus, please help us!’ The rest of us looked at her in amazement when we realized that her agnosticism had been disproved by words from her own mouth. “
