Why God’s Word Must Be Our Authority in Faith, Worship, and Christian Living
When it comes to faith and worship, every Christian must ask: Is what we believe and practice from heaven, or from men?
It is a question that goes to the very heart of our relationship with God. Are we following what Jesus and His apostles taught, or have we let human traditions, popular opinions, and personal preferences shape how we serve the Lord?
In Matthew 21:23–27, during the final week of His earthly ministry, the chief priests and elders confronted Jesus. They questioned His authority, asking who had given Him the right to teach and do the things He was doing.
Jesus answered their challenge with a question of His own. He asked whether John’s baptism came from heaven or from men.
The religious leaders found themselves in a difficult position. If they said John’s baptism came from heaven, they would have to explain why they had not believed him. If they said it came from men, they feared the reaction of the people who regarded John as a prophet.
Rather than answer honestly, they said they did not know.
That encounter teaches us an important principle: Religious authority must come from God, not from men’s opinions or traditions.
And that principle should guide everything we believe, teach, and practice today.
Jesus Christ Has All Authority
Before we can determine whether a religious practice comes from heaven, we must understand where divine authority begins.
Following His resurrection, Jesus declared in Matthew 28:18:
“All authority has been given to Me in heaven and on earth.”
Think about the significance of those words. Jesus did not claim to possess some authority or authority limited to certain areas of life. He declared that all authority had been given to Him.
That means our faith and worship must begin with Jesus Christ.
But Jesus also entrusted His apostles with the responsibility of proclaiming His message to the world.
In John 13:20, Jesus spoke of receiving those whom He sends. In 2 Corinthians 5:20, Paul described the apostles as ambassadors for Christ. Just as an ambassador represents the authority of the one who sends him, the apostles were commissioned to proclaim the message of Jesus.
Christ did not leave them to rely on their own understanding or memory.
In John 14:26, Jesus promised that the Holy Spirit would teach them and remind them of what He had spoken.
Through the Holy Spirit’s work, the apostles were equipped to faithfully communicate Christ’s teachings.
This helps us understand why Acts 2:42 tells us the early Christians continued steadfastly in the apostles’ doctrine.
They understood that the apostles were not simply offering religious opinions. They were delivering Jesus Christ’s teachings.
If we want to follow Christ, we must take seriously what He taught through His apostles.
God’s Word Is Sufficient
One central truth of this message is that God has already provided what we need to know about salvation, godliness, and faithful Christian living.
Second Peter 1:3 teaches that God’s divine power has given us everything we need for life and godliness.
Jude 3 speaks of the faith that was delivered once for all to the saints.
And 2 Timothy 3:16–17 reminds us:
“All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.”
Consider what that means.
God has not left us without direction. We do not need to invent new doctrines or depend upon modern revelations to discover how He wants us to live.
Scripture provides the instruction, correction, and guidance we need to equip us for every good work.
But knowing Scripture is sufficient and letting it govern our lives are two different things.
We must be willing to examine what we believe and ask whether God’s Word genuinely supports it.
The Majority Is Not Always Right
One of the greatest dangers we face is allowing popular opinion to determine what we believe.
How often do we hear someone defend a practice simply because everyone else is doing it?
But popularity has never been the standard of truth.
In Matthew 7:13–14, Jesus warned about the broad way that leads to destruction and the narrow way that leads to life.
The broad way is attractive because so many people travel it. Yet the number of people following a path does not determine whether it is right.
Think about the days of Noah.
Most people did not heed God’s warning. Their numbers did not protect them from judgment when the flood came.
We see a similar lesson in Israel’s wandering in the wilderness. The people’s unbelief and disobedience brought serious consequences, even though many shared the same attitudes.
These examples remind us that truth is not determined by a vote.
We cannot assume something is right simply because society accepts it, a large congregation practices it, or generations of believers follow it.
Our responsibility is not to follow the crowd. Our responsibility is to follow Christ.
Family Traditions Must Be Examined
Many of us learned religious beliefs from our parents and grandparents.
We respect them, love them, and appreciate the influence they have had on our lives. But we must still examine inherited beliefs in light of Scripture.
Sometimes, when we share God’s Word with others, we hear a familiar response: My parents believed this, and that is good enough for me.
Yet Jesus teaches us that our loyalty to Him must come before every other earthly relationship.
In Matthew 10:37, Jesus reminds us that anyone who loves father or mother more than Him is not worthy of Him.
This does not mean we should dishonor our parents. It means that even those we love and respect cannot replace Christ as the authority in our lives.
If every generation had simply accepted the religion of its ancestors without question, many would never have turned away from idolatry to serve the living God.
We honor our families best when we seek the truth and obey God.
And that may require us to examine beliefs we have accepted for many years.
Don’t Follow a Preacher Blindly
Another danger arises when we place too much confidence in religious leaders.
It is easy to assume that a preacher, pastor, or other religious teacher must be correct because of his position, education, or years of experience.
But no human teacher is beyond error.
Jesus warned about blind guides leading others into a ditch. Paul also warned in 2 Corinthians 11 about the danger of being deceived by false teachers.
That should concern every one of us.
We should appreciate faithful teachers who devote themselves to studying and proclaiming God’s Word. But we must never elevate their words above Scripture.
Acts 17:11 gives us a wonderful example in the Bereans.
When Paul preached to them, they received the message with readiness, but they also searched the Scriptures daily to determine whether what they were hearing was true.
Think about that. Even when listening to the apostle Paul, they examined the Scriptures.
Shouldn’t we do the same today?
When you hear a sermon, attend a Bible class, or listen to a religious teaching, don’t simply accept it because the person speaking sounds knowledgeable or convincing.
Open your Bible. Read the passage. Examine the context. Determine whether the teaching agrees with God’s Word.
A preacher’s teaching is only as trustworthy as the biblical authority behind it.
Human Creeds and Traditions Cannot Replace Scripture
Throughout history, religious groups have developed creeds, statements of belief, and traditions to express their doctrines.
But this raises a concern: what happens when human statements begin to govern faith and worship instead of Scripture?
Questions concerning infant baptism, baptism by immersion, the permanence of salvation, and various worship practices illustrate why we must carefully examine the biblical basis for what we teach.
The message challenges us to consider whether Christ and His apostles established these practices or whether later human traditions developed them.
And it makes a pointed observation about religious creeds.
If a creed teaches more than Scripture, it goes beyond what God has revealed. If it teaches less, it leaves something out. If it teaches exactly what Scripture teaches, why not simply rely on the Bible itself?
The call is to let God’s Word be our final authority.
That requires more than claiming we believe the Bible. It means being willing to change a cherished tradition or long-held conviction when careful study shows it is not consistent with Scripture.
Are we willing to do that?
Are we more committed to defending what we have always practiced, or to discovering what God has actually commanded?
Our Conscience Must Be Guided by Truth
Perhaps you have heard someone say, “Just let your conscience be your guide.”
That sounds reasonable. But can we always trust our conscience?
Consider the apostle Paul.
In Acts 23:1, Paul stated that he had lived before God in good conscience. Yet Acts 26:9–11 describes how he once believed he should oppose the name of Jesus and persecute Christians.
Paul sincerely believed he was doing the right thing. But he was sincerely wrong.
That teaches us an important lesson: A clear conscience does not necessarily mean we are following God’s will.
The message illustrates this truth by comparing our conscience to a clock.
A clock can run perfectly and still show the wrong time if it hasn’t been properly set.
Our conscience works similarly. We must train and correct it with the truth of God’s Word.
We may feel comfortable with a particular belief or practice because we have followed it for years. But familiarity and sincerity do not automatically make something right.
We must continually allow Scripture to shape our conscience and understanding.
Understanding the Old and New Covenants
Another important question concerns the relationship between the Old and New Testaments.
The Old Testament remains a valuable part of God’s inspired Word. It teaches us about His character, His promises, His dealings with Israel, and His unfolding plan of redemption.
But we must also understand the purpose of the law given through Moses.
Galatians 3:19 explains that the law was added because of transgressions until the promised Seed would come.
Paul describes the law as a tutor leading to Christ. Then in Galatians 3:25, he explains that with the coming of faith, God’s people are no longer under that tutor.
Romans 7:4 likewise teaches that believers have become dead to the law through the body of Christ.
The message applies these teachings to questions about worship practices, including Sabbath observance, burning incense, instrumental music, and the distinction between clergy and laity.
Its central argument is that Christians must look to the teachings of Christ and His apostles for authority under the new covenant rather than assuming that every practice authorized under the Mosaic covenant carries forward unchanged.
Yet this does not mean the Old Testament has no value.
Romans 15:4 tells us that the things written before were written for our learning, so that through patience and the comfort of the Scriptures we might have hope.
We still need to study the Old Testament. Its history, warnings, promises, and examples teach us valuable lessons.
We simply must understand those Scriptures in light of Christ and the new covenant He established.
We Must Search the Scriptures Daily
So how do we protect ourselves from being misled?
The answer is not complicated, but it requires effort and commitment.
Acts 2:42 tells us the early Christians continued steadfastly in the apostles’ doctrine.
Acts 17:11 tells us the Bereans searched the Scriptures daily.
Notice that word: daily.
God’s Word was not intended to be opened only during a Sunday worship service or when someone else is teaching us.
We need regular time in Scripture because our minds forget, our understanding needs correction, and the world continually presents us with competing ideas.
The more familiar we become with God’s Word, the better prepared we are to recognize teachings that do not agree with it.
We should ask ourselves: Are we studying Scripture enough to recognize biblical truth? Are we testing what others teach, or merely trusting their words? And when Scripture challenges something we have always believed, are we willing to listen?
Spiritual growth requires humility. It requires a willingness to be corrected, the discipline to study, and the courage to follow truth even when it’s unpopular.
Is Your Faith Built on God’s Word?
As we consider the question Jesus asked about John’s baptism, we should ask the same question in our own lives.
Is what we believe from heaven or from men?
Is our worship guided by God’s revealed will or by human preference?
Have we accepted certain religious practices simply because they are popular, because our parents taught them, or because a preacher told us they were right?
Or have we searched the Scriptures for ourselves?
We cannot afford to be careless about these questions.
Jesus warned that blind leaders can lead others astray. Scripture warns that false teaching can deceive those who do not remain grounded in the truth.
But God has provided His Word to guide us.
We have the teachings of Christ and His apostles. We have the Scriptures to instruct, correct, and equip us. And we have the responsibility to study them faithfully.
If we discover that something we believe or practice is wrong, we must be willing to correct it. And when we discover what is right, we should faithfully practice it and share it with others.
The invitation is simple but deeply personal.
Don’t follow a teaching merely because it is popular. Don’t accept it merely because it is traditional. Don’t believe it simply because a preacher says it. Open God’s Word and examine it for yourself.
As we seek to worship and serve the Lord, may we continually return to the question that Jesus placed before the religious leaders:
Is it from heaven, or is it from men?
Our answer should shape not only what we believe, but also how we worship, live, and faithfully follow Jesus Christ.
