Jesus: The Measure of Truth

Jesus: The Measure of Truth John 14:1–6

Take your copy of God’s Word and turn with me to John 14:1–6. We will begin here and look at several other passages, so keep your Bible close.

Throughout this series, we have considered how to recognize error, why sound doctrine matters, and how to stand firm when so many voices compete for our attention. But there is a question we must ask before we go any further: What is all this discernment supposed to accomplish? If we become better at identifying false teaching but do not grow in our love for Jesus, we have missed its purpose. God has given us truth so that we might know His Son, trust His Word, and follow Him faithfully

Imagine a man who installs an elaborate security system around his home. He checks every window and watches every camera, but becomes so consumed with protecting the house that he neglects the family inside. He has forgotten what makes the house precious. Discernment also protects something precious: our faithfulness to Christ and the gospel that brings us to Him.

Let us read John 14:1–6.

John 14:1–6 NKJV

1 “Let not your heart be troubled; you believe in God, believe also in Me. 2 In My Father’s house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. 3 And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also. 4 And where I go you know, and the way you know.” 5 Thomas said to Him, “Lord, we do not know where You are going, and how can we know the way?” 6 Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.

In John 14, Jesus is speaking to troubled disciples on the night before His crucifixion. He has told them He is leaving, and they do not understand where He is going. Thomas asks how they can know the way. Jesus answers by directing them to Himself: “I am the way, the truth, and the life. No one comes to the Father except through Me” (John 14:6).

These words offer real comfort because they make a definite claim. Their hope rests in the One speaking to them. Jesus is the way to the Father because He alone reconciles sinners to God. He is the truth because He perfectly reveals God. He is the life because eternal life is found in Him. That is the central truth of this message: We grow in discernment as we know, trust, and follow the Jesus revealed in Scripture.

1. Know the Christ Who Reveals the Father.

Before we can measure a teaching by Jesus, we must be certain we know who Jesus is. Many people speak warmly about Him. They may call Him a great teacher, an inspiring example, or a prophet. But admiration for Jesus is not the same as believing what Scripture says about Him.

[Read John 1:1–3, 14.]

John 1:1–3 NKJV

1 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 nothing was made that was made.

John 1:14 NKJV

14 And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.

John takes us back before Bethlehem, before Abraham, and before creation. When the beginning began, the Word already existed. The Word was with God, and the Word was God. John distinguishes the Son from the Father while declaring the Son’s full deity. Then he tells us that this eternal Word became flesh. Jesus did not begin to exist when Mary gave birth to Him. The eternal Son entered our world and took on a real human nature.

This matters because we need more than someone who offers an opinion about God. We need God to make Himself known. Jesus is fully God and fully man. He is qualified to reveal the Father and to stand in our place as our Savior.

Hebrews 1:1–3 NKJV

1 God, who at various times and in various ways spoke in time past to the fathers by the prophets, 2 has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds; 3 who being the brightness of His glory and the express image of His person, and upholding all things by the word of His power, when He had by Himself purged our sins, sat down at the right hand of the Majesty on high,

Hebrews 1.1-3 tells us that God spoke through the prophets and has now spoken through His Son, who perfectly reveals His glory and nature.

When we look at Jesus in Scripture, we see God’s compassion toward the broken, His holiness in the presence of sin, and His authority over creation. We must receive the whole picture. We cannot select His kindness and ignore His commands, or emphasize His judgment while forgetting His mercy. The Christ of Scripture does not change to fit our preferences.

Suppose someone gives you a portrait of a person you know well. The picture is beautifully framed, and the artist has used wonderful colors. But the face is wrong. A beautiful frame cannot make it an accurate portrait. In the same way, impressive music, moving stories, and familiar Christian language cannot make a distorted presentation of Jesus true.

When you listen to a teacher, ask what that person says about Jesus. Does the teaching confess His deity and humanity? Does it honor His authority? Does it agree with what He says about sin and salvation? We answer those questions from Scripture. Our personal impression of Jesus must always submit to God’s written revelation of Him.

2. Read the Scriptures that point to Christ

Once we understand who Jesus is, we begin to see why the Bible continually directs our attention toward Him. Knowing Christ means giving careful attention to the Scriptures that reveal Him.

Luke 24:25–27 NKJV

25 Then He said to them, “O foolish ones, and slow of heart to believe in all that the prophets have spoken! 26 Ought not the Christ to have suffered these things and to enter into His glory?” 27 And beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself.

Two disciples are walking toward Emmaus after the crucifixion. They are discouraged because they had hoped Jesus would redeem Israel. They know what happened in Jerusalem, but they do not understand how His suffering fits the promises of God. The risen Jesus joins them and explains what the Scriptures teach concerning Himself.

Notice how He helps them. He opens the Scriptures. Their understanding needs to be corrected by what God has already said. The cross had not defeated God’s plan. Christ’s suffering and entrance into glory fulfilled it.

Later, in Luke 24:44–47, Jesus again explains that the Scriptures anticipated His suffering, resurrection, and the proclamation of repentance for the forgiveness of sins in His name.

The Bible tells the unfolding story of God’s saving work, and that story reaches its fulfillment in Jesus Christ. The sacrifices help us understand the need for atonement. The priesthood prepares us to understand His work as our great High Priest. The promises concerning David’s throne point us toward the coming King. These connections belong to the Bible’s own message.

That does not mean we should invent a hidden reference to Jesus in every detail. We must first ask what a passage says, who is speaking, and what it meant in its setting. Then we consider how it fits within the whole counsel of God. Reading the Bible with Christ at the center requires careful study.

We should also be careful about making ourselves the center of every passage. Scripture certainly teaches us how to live, but its message is greater than advice for becoming successful or overcoming personal obstacles. It reveals our sin, displays God’s faithfulness, and directs us to the Redeemer we need.

In John 5:39–40, Jesus confronts people who study the Scriptures yet refuse to come to Him for life. That is a sobering warning for anyone who has spent years around a Bible. We can become familiar with biblical facts while resisting the Savior’s authority. As we study, we should ask, “What does this passage teach me about God? What does it call me to believe or obey?” Understanding should lead us to trust Him.

3. Rest in the Savior who sets sinners free

The Scriptures lead us to Christ because He alone can meet our deepest need. We need forgiveness, reconciliation with God, and deliverance from the slavery of sin.

[Read John 8:31–36.]

John 8:31–36 NKJV

31 Then Jesus said to those Jews who believed Him, “If you abide in My word, you are My disciples indeed. 32 And you shall know the truth, and the truth shall make you free.” 33 They answered Him, “We are Abraham’s descendants, and have never been in bondage to anyone. How can You say, ‘You will be made free’?” 34 Jesus answered them, “Most assuredly, I say to you, whoever commits sin is a slave of sin. 35 And a slave does not abide in the house forever, but a son abides forever. 36 Therefore if the Son makes you free, you shall be free indeed.

Jesus speaks about knowing the truth and being made free. His listeners appeal to their relationship to Abraham, but Jesus exposes a bondage that family heritage cannot remove. Those who practice sin are enslaved to sin. His promise of freedom addresses the spiritual condition of the human heart.

A person may have opportunities, education, financial security, and a good reputation while still being a slave to sin. We cannot remove our guilt by becoming better informed. We cannot reconcile ourselves to God by comparing ourselves with someone worse. We need the Son to set us free.

This is why the gospel must remain central. Paul summarizes its message in 1 Corinthians 15:3–4: Christ died for our sins according to the Scriptures, was buried, and rose again on the third day according to the Scriptures. Jesus lived without sin, gave Himself for sinners, and rose victorious over death. Our acceptance before God rests upon His saving work.

1 Corinthians 15:3–4 NKJV

3 For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He rose again the third day according to the Scriptures,

Ephesians 2:8–10 makes the relationship between grace and obedience clear. Salvation is God’s gift, received through faith, apart from works. Those whom He saves are then created in Christ for good works. Obedience is the fruit of salvation; it cannot purchase salvation. We do not bring God a record impressive enough to earn His favor. We come trusting the Savior He has provided.

Repentance belongs with that response of faith. We turn from sin and self-reliance to Christ. Repentance is not a payment we offer for forgiveness, and it does not mean we must repair our lives before we can come. We come as sinners who need mercy, trusting Jesus to forgive and change us.

That gives us an essential question for evaluating any message: Where does this teaching tell me to place my confidence? If it makes my religious performance the basis of acceptance with God, it undermines Christ’s sufficiency. If it promises forgiveness while encouraging me to remain comfortable in sin, it misrepresents the freedom He gives. The Savior who forgives His people also begins transforming them.

Christians, never graduate beyond this gospel. On the day you see your weakness most clearly, your hope is still Jesus. Confess your sin and return to Him. Your failures must be taken seriously, but His sacrifice must be taken seriously too. The One who saves is sufficient to sustain His people.

4. Reflect the character of the Lord you confess

Christ’s saving grace changes our standing before God, and it begins changing the way we live. That brings discernment close to home. We must examine how we handle the truth we profess to believe.

Philippians 2:3–8 NKJV

3 Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. 4 Let each of you look out not only for his own interests, but also for the interests of others. 5 Let this mind be in you which was also in Christ Jesus, 6 who, being in the form of God, did not consider it robbery to be equal with God, 7 but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 8 And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross.

Paul addresses selfish ambition and pride within the church by directing believers to Christ. The eternal Son humbled Himself, took the form of a servant, and obeyed the Father even to death on a cross. His humility never diminished His deity. It displayed the self-giving character His people are called to reflect.

We need that reminder when discussing discernment. It is possible to defend an accurate statement with an arrogant spirit. We may identify someone else’s error while ignoring our own impatience or desire to win. Being right about a doctrine does not give us permission to be wrong in how we treat people.

Jesus was compassionate, and He was firm. He confronted hypocrisy and warned of judgment. He welcomed sinners and called them to repentance. We must let all of His ministry shape us. Gentleness does not require silence about error, and courage does not require contempt for the person who is mistaken.

Second Timothy 2:24–26 calls the Lord’s servant to patience, the ability to teach, and humble correction. That means we can speak plainly while remembering our own need for grace. The person before us is someone to help, not someone to humiliate. Our aim is that people understand the truth and turn to God.

This also helps us evaluate ministries. Is the teaching cultivating dependence upon Christ, or fascination with a personality? Does it encourage holiness, humility, and love? A pleasant personality cannot make false doctrine true, and an imperfect believer does not make sound doctrine false. Scripture judges the message, while the pattern of a teacher’s life also deserves careful attention (Matthew 7:15–20).

Let us bring the question back to ourselves. Is our study making us more teachable? Are we quicker to confess sin? Are we more patient with people who are still learning? Growing in discernment should help us become more like the Savior whose truth we defend.

5. Follow the Shepherd who keeps His people

As we seek to grow, we soon discover how much we still need to learn. The number of competing voices can feel overwhelming. Jesus gives His people a foundation for confidence in His faithful care.

John 10:27–30 NKJV

27 My sheep hear My voice, and I know them, and they follow Me. 28 And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. 29 My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father’s hand. 30 I and My Father are one.”

Jesus describes His sheep as those who hear His voice and follow Him. He knows them, gives them eternal life, and promises that they will never perish. Their security rests in the care of the Son and the Father.

Hearing the Shepherd’s voice is not permission to treat every inward impression as a message from God. We recognize and follow the Jesus revealed in Scripture. The Holy Spirit helps us understand and receive God’s Word; He does not lead us to contradict it. Our feelings and experiences must be tested by what God has spoken.

Familiarity grows through attention. When you have listened to someone you love for many years, you recognize the way that person speaks. Likewise, regular study of Scripture helps us recognize teaching that misrepresents our Lord. That growing familiarity must remain grounded in the text, because even mature believers can be mistaken.

Keep opening your Bible. Listen carefully when it is preached. Ask questions, examine the passages, and welcome correction. Stay close to the people God has given you in the local church. These are ordinary ways the Shepherd strengthens His flock.

And follow Him when the road becomes difficult. Faithfulness does not guarantee that every prayer will be answered as we hoped or every circumstance explained. But the Shepherd who laid down His life for His sheep has shown us His love. We can trust His character when we cannot understand His purposes.

Our confidence finally rests in His grip upon us. We pursue discernment because He commands it, but our hope is not that we will become incapable of making mistakes. Our hope is that Jesus is faithful. He knows His sheep, and He will keep His promises.

Come to Christ and keep following Him

As we bring this message to a close, let us consider where our study of truth is leading us. Are we trusting the Jesus revealed in Scripture? Are we resting in His finished work? Are we submitting to His Word in the ordinary decisions of life?

You may know Christian language and still need to come to Christ. Church attendance, family history, and biblical knowledge cannot forgive your sins. Jesus can. Turn from your sin and trust the Savior who died and rose again. He is the only way to the Father, and His invitation to come is real.

For those who belong to Him, perhaps the needed response is to return to attentive obedience. Bring Him the pride, distraction, or tolerated sin His Word has exposed. Open your Bible with a willing heart, and follow what He says. We study truth because we want to know Him, and we guard against error because we want to remain faithful to Him.

Jesus is the measure of truth. Let us keep our confidence in His saving work and our lives under His authority.

Closing Prayer

Father, thank You for making Yourself known through Your Son and for giving us Your Word. Keep us from handling truth proudly or neglecting what You have taught us. Give us understanding, humble hearts, and courage to obey. Draw those who are lost to faith in Christ, and strengthen Your people to rest in His finished work. Help us to know our Shepherd through Scripture and follow Him faithfully. In Jesus’ name, amen.
