The dangerous thing is when the feelings of sin are aroused in a person, like lust, envy, or other feelings, so he tries to ignore their existence, and thinks that if these feelings were truly present, they would defile him. There is a difference, however, between a person who admits the existence of these feelings and then deals with them to make them godly feelings, and [a person who] ignores and suppresses them. When a person deals with these feelings and reveals them to the light of Christ, he is sanctified. But if he ignores and denies their existence, they will remain buried within him, and they may come out violently at some point in time, thereby causing devastation in his life.

—H.E. Metropolitan Youssef, How to Develop Your Personality
