We don’t remember who said this but it is worth repeating:

“The glory of a good man is the testimony of a good conscience. Therefore, keep your conscience good and you will always enjoy happiness, for a good conscience can bear a great deal and can bring joy even in the midst of adversity. But an evil conscience is ever restive and fearful. Sweet shall be your rest if your heart does not reproach you. Do not rejoice unless you have done well. Sinners never experience true interior joy or peace, for ‘there is no peace to the wicked,’ says the Lord. Even if they say: ‘We are at peace, no evil shall befall us and no one dares to hurt us,’ do not believe them; for the wrath of God will arise quickly, and their deeds will be brought to naught and their thoughts will perish.”
