When you perceive in yourself something worthy of praise, and you feel a desire to tell others about it, try immediately to destroy this desire with the thought that you will not receive any benefit from relating it, but only harm. People are very fickle in their opinions: what they praise today, they forget or even condemn tomorrow. And of course, by telling of what is praiseworthy in you, you are making yourself unworthy of praise from God, because you are receiving your reward from people. ‘Assuredly, I say to you, they have their reward,’ said the Lord of people of this type (Matt 6:5). Also, try always to remember these important words of the Lord: ‘Woe to you when all men speak well of you.’ (Luke 6:26)”
