16 For where you have envy and selfish ambition, there you find disorder and every evil practice.
28 Furthermore, since they did not think it worthwhile to retain the knowledge of God, he gave them over to a depraved mind, to do what ought not to be done. 29 They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, 30 slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; 31 they are senseless, faithless, heartless, ruthless. 32 Although they know God's righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.
30 A heart at peace gives life to the body, but envy rots the bones.
17 Do not let your heart envy sinners, but always be zealous for the fear of the LORD.
20 He went on: “What comes out of a man is what makes him ‘unclean.’ 21 For from within, out of men's hearts, come evil thoughts, sexual immorality, theft, murder, adultery, 22 greed, malice, deceit, lewdness, envy, slander, arrogance and folly. 23 All these evils come from inside and make a man ‘unclean.’”
“All the commandments of God are commandments of love tending to our real good and great happiness; far from being grievous to those who have faith and love, the practice thereof is life and peace. The world may think it a grievous burden; but this is a great mistake indeed. Sin is grievous. In hatred, envy, anger, revenge, pride, there is nothing but torment and slavery; but in love there is a sweet rest and pleasure. Thus a sinner always punishes himself, and is robbed of great peace and blessing, by transgressing the commandments of God.” K. H. Von Bogatzky
“Let us note how far from satisfactory is the state of those who are content with sound doctrinal opinions, and orthodox correct views of the Gospel, while in their daily life they give way to ill-temper, ill-nature, malice, envy, quarrelling, squabbling, bickering, surliness, passion, snappish language, and crossness of word and manner. Such persons, whether they know it or not, are daily proclaiming that they are not Christ’s disciples. It is nonsense to talk about justification, and regeneration, and election, and conversion, and the uselessness of works, unless people can see in us practical Christian love.” John Charles Ryle
“Envy is a denial of providence.” Stephen Charnock
“Envy of another man’s calling can work havoc in our own.” Watchman Nee
“Many aspects of the flesh are disarmed and eliminated by a deep apprehension of our justification by faith. Faith in Christ cures unbelief, anxiety, and insecurity, and in so doing it cuts the roots of envy, jealousy and a host of related egocentric fleshly patterns.” Richard Lovelace
