But although God can alter and change the most diverse natures, yet in my mind a mystery is of more avail than a miracle. For what else than stones were they who bowed down to stones, like indeed to them who made them. It is prophesied therefore that faith shall be poured into the stony hearts of the Gentiles, and through faith the oracles promise that Abraham shall have sons. But that you may know who are the men compared to stones, he has also compared men to trees, adding, For now the axe is laid to the root of the tree. This change of figure was made, that by means of comparison might be understood to have now commenced a more kindly growth of manhood.
