"... love does not envy..." 1 Corinthians 13:4
The word "love" is better translated "charity," referring to love in action, but the idea is the same. An envious Christian is lacking in love. And the entire context of 1 Corinthians 13 is that the actions of a person without charity are in vain.
Envy is sometimes the result of an empty life. Surprisingly, the cure for an empty life is "charity." When you put love into action, you'll find things to do that will make your life worthwhile.
