John Chrysostom

Then, lest any think that they will simply be deprived of rest only, he adds also the punishment, saying, "For the Word of God is quick, and powerful; and sharper than any two-edged sword, and pierceth even to the dividing asunder of soul and spirit, and of the joints and marrow: and is a discerner of the thoughts and intents of the heart." Here he is speaking of Hell and of punishment. "It pierceth" (he says) into the secrets of our heart, and cutteth asunder the soul. Here it is not the failing of carcasses nor, as there, the being deprived of a country, but of a heavenly kingdom; and being delivered to an everlasting hell, and to undying punishment and vengeance.
