This is such a profound truth from the very lips of our Lord but, I fear, Christians are afraid to contemplate what it means and its repercussions, probably due to it being used by disingenuous people to attack private property and our market economy, what Marx maliciously labeled "Capitalism."
That's a shame.
Actually that statement is from St. Paul: 1 Timothy 6:10
Our Lord said, “Ye cannot serve God and mammon.” Matthew 6:24
