Isaac Samuel Reggio,
A Guide for the Religious Instruction of Jewish Youth
“ In the moment we are struck by some grave calamity, when we see fond hopes, long cherished, vanish in an instant, or when we are on the point of losing what is dearest to us, why is faith in God and in His providence not then weakened in the religious man? Why, on the contrary, does he cling to it more and more? The reason is, because such a faith is not a cold theorem, against which some doubt may eventually arise, but a truth rooted in the love inherent in our nature; and consequently it acquires vigour with the growth of love, and its power cannot be extinguished but when we cease to love. ”
