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. Ye cannot serve God and mammon.
The impossibility of living for God and for materialism is stated here in terms of masters and slaves. No one can serve two masters. One will inevitably take precedence in loyalty and obedience. So it is with God and mammon. They present rival claims and a choice must be made. Either we must place God first and reject the rule of materialism or we must live for temporal things and refuse God‘s claim on our lives.
