Blessed are those who are persecuted for the sake of righteousness, for theirs is the Kingdom of heaven. (Mt. 5:10)
Christ asks us to not be afraid; remember that those who are controlled by the devil are always deathly afraid. Therefore trust in Him and remember that according to the Talmud God says to us: With thy very wounds I will heal thee. If you are unhappy it is because of sin therefore seek the healing that Christ gives in the sacrament of confession and receive joyfully the Holy Eucharist.
