Just as a good act performed without genuine faith is quite dead and ineffective, so too faith alone without works of righteousness does not save us from eternal fire; for ‘he who loves Me’, says the Lord, ‘will keep My commandments’, (cf. John 14:45, 23). If, then, we love the Lord and believe in Him, we shall exert ourselves to fulfill His commandments, so as to be granted eternal life. But how can we call ourselves faithful if we neglect to keep His ordinances, which all creation obeys, and if, although we have been honored above all creation, we are the only creatures who disobey the Creator and show ourselves ungrateful to our Benefactor?
