God's Revelation of the Human Heart

I very much wanted to believe in God; but I could not deceive myself: I had no faith. "And suddenly there came a second, when somehow for the first time I saw (as if a door had opened from a dark room into the sunny street), and in the next second I already knew for sure that God exists... I call this moment the greatest miracle because this precise knowledge came to me not through reason but by some other way... And so by such a miracle my new spiritual life began, which helped me to endure another thirteen years of life in concentration camps and prisons."
