Romans 1:28–32 (NKJV)

28 And even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things which are not fitting; 29 being filled with all unrighteousness, sexual immorality, wickedness, covetousness, maliciousness; full of envy, murder, strife, deceit, evil-mindedness; they are whisperers, 30 backbiters, haters of God, violent, proud, boasters, inventors of evil things, disobedient to parents, 31 undiscerning, untrustworthy, unloving, unforgiving, unmerciful; 32 who, knowing the righteous judgment of God, that those who practice such things are deserving of death, not only do the same but also approve of those who practice them.

This morning we continue studying Paul’s catalogue of the bitter fruits produced by those of debased mind, those whom God in His justice has handed over to their sin for their rebellion. Today, we consider Paul’s assertion that people of debased mind “are untrustworthy.”

To be untrustworthy is to be unreliable, unstable, changeable, or fickle; it is to prove oneself unworthy of trust. To be untrustworthy is a serious character flaw. This is the type of person who makes a promise and fails to keep it; who swears an oath and breaks it; who joins a cause and deserts it. So Solomon compares an untrustworthy man to a bad tooth or a sprained ankle: “Confidence in an unfaithful man in time of trouble Is like a bad tooth and a foot out of joint” (Prov 25:19). There you were chewing that steak when, “Ow!”, your tooth betrayed you. So the chief cupbearer failed to remember Joseph after Joseph had given him comfort in prison; King Saul failed to obey the word of the Lord when Samuel commanded him to wait to sacrifice; the men of Israel in the prophet Malachi’s day covered their garments with blood by divorcing their wives unjustly; Judas betrayed our Lord with a kiss; all these men were, in varying degrees, untrustworthy.

An untrustworthy character is the fruit of worshiping an untrustworthy god – whether that god is other people, oneself, riches, fame, comfort, etc. Those who are untrustworthy stand upon a rickety platform not a solid rock. “Thus says the LORD: ‘Cursed is the man who trusts in man And makes flesh his strength, Whose heart departs from the LORD’” (Jer 17:5). God alone is a sure and certain rock, an immoveable foundation. Jesus died and rose again to reconcile us to that trustworthy God so that we, in turn, might become trustworthy men and women. As we shall sing in Psalm 62 today (62:5-7):

In silence bide I God alone And He shall hear me from His throne; He is my hope and my salvation. He only is my rock and stay, My fortress and my help for aye, And none shall shake my place and station.

The trustworthy man relies upon his trustworthy God and is not moved by the turmoil about him. He is not “tossed to and fro by every wind of doctrine” (Eph 4:14) but remains fixed on Christ. So the trustworthy man “swears to his own hurt and does not change” (Ps 15:4). While a talebearer reveals secrets, a trustworthy man “conceals a matter” (Pr 11:13). A trustworthy man lets his, “Yes,” be, “Yes,” and his, “No,” be, “No.” He doesn’t look for ways to wriggle out of what he has said. He is faithful to his word, faithful to his wife, faithful to his kids, faithful to his employer, faithful to his church, faithful to his neighbor, faithful to his charge. So God instructs us through the prophet Zechariah:

“These are the things you shall do: Speak each man the truth to his neighbor; Give judgment in your gates for truth, justice, and peace; Let none of you think evil in your heart against your neighbor; And do not love a false oath. For all these are things that I hate,’ Says the Lord.”” (Zech 8:16–17)

So what of you? Are you trustworthy? If you’ve promised something, do you fulfill it? If you’ve given your word, do you keep it? If you’ve been given a charge, is it safe with you? Are you like the men the high priest Jehoida chose to receive the offerings for the temple, who didn’t even have to be supervised because they were trustworthy (2 Kgs 12:15)? Or are you untrustworthy? Do you give your word and then look for better, more exciting, or more profitable options?

Reminded of our calling to reflect God’s trustworthy character in our own, let us confess that we have often failed to do so; that we have often violated our oaths and pledges, betrayed the trust of others. We will have a time of silent confession followed by the corporate confession found in your order of service. As you are able, let us kneel together as we confess.
