No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. You cannot serve God and mammon.
All Commentaries on Matthew 6:24 Go To Matthew 6
George Leo Haydock
Behold here a fresh motive to detach you from the love of riches, or mammon. We cannot both serve God and the world, the flesh and the spirit, justice and sin. The ultimate end of action must be one, either for this or for the next life. (Haydock)
