Imagine a pilot flying through thick clouds.
He cannot see the horizon. He cannot see the ground. Everything outside the cockpit is white, and without a visible reference point, his senses can begin lying to him.
He may feel as though the plane is climbing when it is actually descending. He may feel like he is flying straight when the plane is slowly turning. In that moment, the pilot has a choice: trust what he feels or trust the instruments in front of him.
Many aviation accidents have occurred because a pilot trusted his senses when the instruments were telling him the truth.
The same danger exists in the church.
Not every lie enters the church looking like a lie. Some lies use Christian vocabulary. They quote Scripture. They promise deeper spirituality and stricter holiness. They feel right, sound right, and may even be taught by someone holding a Bible right.
But sincerity does not determine truth. Spiritual language does not determine truth. Our feelings do not determine truth.
God’s Word determines truth.
In our passage today, Paul reminds Timothy that God’s Word is the instrument of truth. It guides and corrects our direction even when our feelings tell us otherwise. Paul points us to Christ, warns us that some will depart from the faith, and exposes a counterfeit holiness that replaces God’s Word with man-made restrictions.
When the spiritual atmosphere becomes cloudy and deception makes it difficult to see, the church must keep its eyes on the instruments Christ left us with.
Main Point: The church must hold fast to God’s truth because spiritual deception often disguises itself as godliness.
14 I hope to come to you soon, but I am writing these things to you so that, 15 if I delay, you may know how one ought to behave in the household of God, which is the church of the living God, a pillar and buttress of the truth.
Paul writes these instructions hoping to visit Timothy soon. We do not know whether Paul made this particular visit. But because he might be delayed, he writes so that Timothy and the Ephesian church will know how they “ought to behave in the household of God.”
The word “ought” translated to dei (die), meaning it is necessary, there is need of, it behooves, is right and proper carries the idea of something necessary or binding.
Paul is not offering helpful suggestions. He is giving instructions concerning how God’s people must conduct themselves.
Q: Why does conduct inside the church matter so much?
Because the church is not our house. It is God’s house.
Paul calls the church three things:
The household of God
The church of the living God
The pillar and buttress of the truth
First, The household of God, We are the household of God. The church is not merely an organization we attend; it is a family to which we belong. God is our Father, and believers are brothers and sisters in Christ.
That means how we treat one another matters. Doctrine matters. Leadership matters. Holiness matters. Even if we differ on secondary things.
You can behave casually in somebody else’s house, but when you realize the house belongs to the living God, everything changes.
Second, The church of the living God Paul calls it “the church of the living God.” Ephesus was filled with temples dedicated to lifeless idols—especially the temple of Artemis. But the church did not belong to a statue made by human hands. It belonged to the living God.
The idols could not see, speak, hear, save, or judge. But the God of the church is alive.
Jeremiah 10:10
But the Lord is the true God; he is the living God, the eternal King.
Third, The pillar and buttress of the truth The church is “a pillar and buttress of the truth.”
A pillar holds something up so it can be seen. A buttress supports and stabilizes a structure. Paul is not saying that the church creates truth or that truth would cease to exist without us. He is saying that God has entrusted the church with the responsibility of holding the truth firmly and displaying it faithfully.
The church receives the truth from God, holds it firmly, and displays it before the world.
Not my truth. Not your truth. The truth.
If the church refuses to proclaim the truth, the world will not be left without teaching. It will simply be taught lies.
The church is not called to make the truth more acceptable. It is called to make the truth visible.
2 Timothy 3:16-17
16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, 17 that the man of God[] may be complete, equipped for every good work.
Paul does not leave ‘the truth’ undefined. The church is not commissioned to uphold vague religious principles. The truth has a name: Jesus Christ.
16 Great indeed, we confess, is the mystery of godliness: He[] was manifested in the flesh, vindicated[] by the Spirit,[]seen by angels, proclaimed among the nations, believed on in the world, taken up in glory.
Paul then gives what appears to be an early Christian confession or hymn:
“He was manifested in the flesh, vindicated by the Spirit, seen by angels, proclaimed among the nations, believed on in the world, taken up in glory.”
Paul and his mysteries, calls this the “mystery of godliness.”
If you’ve been here for a little while, we know Paul talks about these mysteries often. In just about every book he writes he tends to slide it in there or lightly mention it.
In Scripture, a mystery is not something impossible to understand. It is something previously hidden that God has now revealed.
And what has God revealed?
Jesus Christ.
“He was manifested in the flesh.” Jesus did not begin to exist in Bethlehem. The eternal Son of God entered human history and took on human flesh.
John 1:1-5
In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things were made through him, and without him was not any thing made that was made. 4 In him was life,[] and the life was the light of men. 5 The light shines in the darkness, and the darkness has not overcome it.
John 1:14
“The Word became flesh and dwelt among us.”
Godliness does not begin with us trying harder. It begins with Christ coming to save sinners.
He was “vindicated by the Spirit.” Jesus was rejected and condemned by men, but the Holy Spirit demonstrated that He truly was the righteous Son of God, especially through His resurrection.
The world said, “Crucify Him.”
God said, “This is My Son.”
He was “seen by angels.” Angels announced His birth, ministered to Him, witnessed His resurrection, and were present at His ascension. Heaven watched the work of redemption unfold.
He was “proclaimed among the nations.” The gospel was never meant to remain inside Jerusalem or belong to one ethnic group. Christ is proclaimed to every tribe, language, people, and nation.
He was “believed on in the world.” The same Jesus rejected by His own people was received by sinners throughout the world.
Finally, He was “taken up in glory.” The crucified Christ is now the exalted Christ. He is not still hanging on the cross, and He is not still lying in the tomb. He is alive, glorified, and reigning.
This is the truth the church must uphold.
The church does not exist to proclaim itself. We proclaim Christ.
…Or so we’re supposed to, some proclaim things Christ never did. Deceiving the masses and leading people away unknowingly. That’s why we, as the church, have to (next point)
4 Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, 2 through the insincerity of liars whose consciences are seared,
Paul moves from the truth concerning Christ to a warning about those who will abandon that truth.
“The Spirit expressly says that in later times some will depart from the faith.”
The word translated “depart” comes from aphistēmi, meaning to withdraw, abandon, or fall away. It is where we get the idea of apostasy, the formal abandonment, disaffiliation, or total renunciation of a religion, political party, or cause by a person who previously held those beliefs.
Notice that Paul says “some will depart from the faith.” These are people who were connected to the visible Christian community and exposed to sound doctrine, but they eventually abandoned what they ‘claimed’ to believe.
They had identified themselves with the Christian faith and had been exposed to the truth, but their departure revealed that their profession could not survive their devotion to deception.
This should not surprise the church. The Spirit has already warned us.
Jesus warned about false prophets in Matthew 7.
“Beware of false prophets, who come to you in sheep's clothing but inwardly are ravenous wolves.
Paul warned the Ephesian elders in Acts 20:29
29 I know that after my departure fierce wolves will come in among you, not sparing the flock; 30 and from among your own selves will arise men speaking twisted things, to draw away the disciples after them.
Wolves in sheep's clothing, preying on the weak, deceiving with twisted Word.
Apostasy rarely begins with someone waking up and saying, “Today I will reject Christianity.”
It usually begins with a small compromise:
“I know what Scripture says, but…”
That “but” has wrecked a lot of people.
I’ve always said, saying “but” cancels everything you said before it.
If you remember 1 Timothy 1:19, Shipwreck is rarely the first decision. It is normally the result of many smaller decisions to ignore the truth.
Paul says these people will devote themselves to “deceitful spirits and teachings of demons.”
False teaching is not merely an intellectual mistake. Behind doctrines that lead people away from Christ is spiritual deception.
Satan does not always attack the church by standing outside and shouting. Sometimes he walks inside carrying a Bible, using Christian vocabulary, and offering teaching that sounds spiritual.
That is what makes deception dangerous. If it looked evil, nobody would follow it.
I personally would go as far to say what scripture you can quote and how elegantly you can speak means little to nothing compared to how well you live it. The first individual to seek power through knowledge over wisdom, is in hell trying to bring you down there with him.
Knowing Scripture is not the same as submitting to Scripture. Satan quoted the Bible to Jesus, but he twisted it in an attempt to deceive Him.
Paul says these teachings come through “the insincerity of liars whose consciences are seared.”
Again, coming full circle to what we went over in 1 Timothy 1, A seared conscience is one that has become insensitive. Repeatedly rejecting the truth eventually damages a person’s ability to recognize and respond to it.
A healthy conscience reacts to sin like skin reacts to heat. It warns us that something is wrong. But scar tissue loses sensitivity.
The danger is not merely committing sin. The danger is becoming comfortable with it.
A person can resist conviction for so long that the silence of his conscience feels like the approval of God.
But silence is not approval.
3 who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. 4 For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, 5 for it is made holy by the word of God and prayer.
The false teachers were forbidding marriage and requiring people to abstain from certain foods. They made these restrictions sound spiritual, but Paul exposes them as false doctrine. Their mistake was treating God’s good creation as though it were inherently sinful.
Marriage was created by God before sin entered the world (Genesis 2:18–24). Food was also created by God and given to humanity to receive and enjoy.
Mark 7:14-16
14 And he called the people to him again and said to them, “Hear me, all of you, and understand: 15 There is nothing outside a person that by going into him can defile him, but the things that come out of a person are what defile him.”[]
Therefore, rejecting these gifts does not automatically make a person more spiritual. There is a kind of self-denial that looks holy on the outside but is actually rooted in a rejection of what God has declared good.
Paul says that these things were created “to be received with thanksgiving by those who believe and know the truth.” The proper response to God’s gifts is not worship, abuse, or rejection—it is thanksgiving. We receive them from His hand, recognize that they belong to Him, and use them according to His Word. We’re oftentimes given the opportunity to be stewards of these things, not owners.
Does this mean that everything people desire must be good? No. Paul does not say that every use of creation is good. Sin takes what God created and twists it outside of His design. Food is good, but gluttony is sin. Marriage is good, but sexual immorality is sin. The problem is not with what God created; the problem is with the sinful heart that misuses it. Again, it’s a heart problem.
“For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving.”
Genesis 1, God repeatedly looked upon His creation and called it good. False religion says, “Do not touch, do not taste, do not marry,” as though holiness comes through man-made restrictions. The gospel teaches us to receive God’s gifts gratefully while submitting their use to God’s authority.
Verse 5 says that the gift “is made holy by the word of God and prayer.” The Word tells us what God has permitted and how His gifts are to be used. Prayer acknowledges that the gift comes from Him and is dependent upon His blessing. Together, the Word and prayer move us away from both sinful indulgence and false asceticism.
The question is not, “Can I have this?” The better questions are: “Can I receive it with thanksgiving and not pride? Can I use it in obedience to God’s Word? Can I pray over it with a clear conscience?”
Holiness is not found in rejecting everything God has made. Holiness is receiving His gifts with gratitude, enjoying them within their God-given boundaries, and refusing to let the gift take the place of the Giver.
The church must know the truth because deception is certain.
We must proclaim Christ because He is the substance of our faith.
And we must test every teaching by the Word of God because not everything that sounds spiritual comes from the Spirit of God.
The church is the pillar of truth—not the playground of opinions.
So what are you trusting to guide your life? Your feelings? The culture? A teacher who tells you what you want to hear? Or the Word of God?
When your feelings disagree with Scripture, trust the Word. When the culture calls truth hateful, trust the Word. When false teachers make deception sound spiritual, trust the Word.
The church must uphold the truth. We must proclaim Christ. We must recognize deception and reject counterfeit holiness.
Do not trust what merely feels right. Hold fast to what God has said.
Let Scripture correct you.
Keep Christ at the center.
Test every teaching.
Guard your conscience.
Receive God’s gifts with gratitude.
