“And the Lord had regard for Abel and his offering; but for Cain and for his offering He had no regard. So Cain became very angry and his countenance fell. And it came about when they were in the field that Cain rose up against Abel his brother and killed him” (Genesis 4:4-5, 8).
It’s not just Cain’s problem. Envy invites each of us to lament the inequities of life. It beckons you to a constant comparison of what others have to what you don’t: the sibling with the happy marriage; the co-worker whose salary is higher; the neighbor with bright, intelligent, well-adjusted kids; the friend with dark hair while yours is graying. Envy is what prompted Cain to kill Abel. And even if envy doesn’t go to this extreme, it will murder your soul nonetheless.
