Who's Your Master?

 “No servant can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon.” Now the Pharisees, who were lovers of money, also heard all these things, and they derided Him.

Luke 16:13–14

We serve many things, but just one master. It is possible to think that we are serving God, but if He is not Master, then eventually push comes to shove. The Pharisees definitely thought that they were serving God. 

You can have office in the church, be meticulous about your doctrine and behavior, be thought of by others as a very holy man and a spiritual leader—and still, God's omniscient assessment of you may be "lover of money." How grievous that would be, dear reader!

God's Providence to Gospel Hypocrites in the Church

"As for those wicked and ungodly men whom God, as a righteous Judge, for former sins, does blind and harden, from them He not only withholds His grace whereby they might have been enlightened in their understandings, and wrought upon in their hearts; but sometimes also withdraws the gifts which they had, and exposes them to such objects as their corruption makes occasion of sin; and, withal, gives them over to their own lusts, the temptations of the world, and the power of Satan, whereby it comes to pass that they harden themselves, even under those means which God uses for the softening of others."

WCF 5.6—a fearful truth for those who outwardly profess faith, but inwardly obtain no spiritual profit in the means of grace, even while those around them are drawing near to God, enjoying His glory, and being edified.
