When you envy somebody, his good makes you sad (and sometimes mad). When you stop envying him, his good makes you glad. Sometimes you don’t realize how sick you were until you get well.
“When at any time you find in your heart motions of envy towards any person, . . . expel the venom of that poisonous passion.” William Law
“Rid yourself of . . . envy. . . .” 1 Peter 2:1
