From the Prologue:
We often complain nowadays that to live according to God s commandments is a difficult struggle. We think that to be truly Christian we have to fast, pray, give alms and perform other such virtuous acts. And as we ponder over the trouble we have to take to be virtuous and live a life in Christ, we lose heart and give up. Christ, however, suggested a very simple and easy way for us to please Him and avoid condemnation at the Last Judgment, saying: Do not judge in order not to be judged (Matt. 7:1-2).
