Beware the sin of envy
"St. Paul tells us, No one can say Jesus is Lord, except in the Holy Spirit (1Cor. 12: 3) and, There is none who does good, no, not even one (Rom. 3: 12). and so when a man envies his brother the good God says or does through him, it is like committing a sin of blasphemy, because he really envying God, who is the only source of every good."
St. Francis of Assisi
