Do not say that it is impossible to achieve a virtuous life, but say that it is not easy. Those who have achieved the virtuous life find it is not easy to maintain. Those who are devout, and whose intellect enjoys the love of God, take part in the life of virtue. The unspiritual intellect, however, is concerned with material things and wavers back and forth, producing both good and evil thoughts. It does this because it is changeable by nature and directed towards material things. But the intellect that enjoys the love of God punishes the evil which arises on its own through human laziness.
