An all-consuming lust for money and/or power destroys everything of real value in one's life- i.e., marriages, family, health and above all a living relationship with God. In fact, that kind of avarice is the symptom of a much deeper-rooted problem, a spiritual cancer that is eating us away from the inside out. There is only One who can set us free.
No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money. (Matt 6:24-25, ESV)
For what does it profit a man to gain the whole world and forfeit his soul? (Mark 8:36)
