The Danger of Confirmation Bias in Faith
Scripture: Luke 6:6–11
On another Sabbath, he entered the synagogue and was teaching, and a man was there whose right hand was withered. And the scribes and the Pharisees watched him, to see whether he would heal on the Sabbath, so that they might find a reason to accuse him. But he knew their thoughts, and he said to the man who had the right hand withered, "Come and stand here." And he rose and stood. And Jesus said to them, "I ask you, is it lawful on the Sabbath to do good or to do harm, to save life or to destroy it?" And after looking around at them all, he said to him, "Stretch out your hand." And he did so, and his hand was restored. But they were filled with fury and discussed with one another what they might do to Jesus. — Luke 6:6–11 (ESV)
Introduction
As we journey through life, we encounter countless pieces of information and many different people. Yet, human nature possesses a fascinating yet dangerous psychological tendency: the inclination to seek out and focus only on evidence that supports what we already believe to be true. Psychologists call this Confirmation Bias.
Confirmation bias goes far beyond simply misunderstanding something due to a lack of information. It is a subtle mechanism of the heart where we selectively accept only the data that flatters our existing thoughts, beliefs, and judgments, while completely ignoring or downplaying any information that challenges them.
For instance, if we dislike someone, even when they do something good, our bias makes us mutter, "What are they scheming now?"
Conversely, if we love someone, even when they commit a clear wrong, we soften it: "They must have had a really good reason."
The danger is that confirmation bias does not stay confined to our daily social lives; it stealthily infiltrates even our most sacred spiritual lives. With our lips, we confess, "I will live according to God's Word," and "I will submit to the Lord's will." Yet, in the actual arena of life, rather than trembling before the voice of God, we handpick only the Bible verses that support our pre-determined agendas and desires. Instead of allowing our narrow views to be broken and reshaped by Scripture, we foolishly turn the Bible into a weapon to justify our own arguments.
Our text today in Luke 6:6–11 vividly exposes how deeply the Pharisees had fallen into confirmation bias regarding Jesus' Sabbath healing ministry. May this passage serve as a spiritual mirror, inviting us to examine our souls and lay down our stubborn biases before the Lord.
1. The Distorted Gaze of the Pharisees and the Heart of Jesus
1) The Scene That Lost the Essence of the Sabbath (6:6–7)
In the preceding verses (Luke 6:1-12), Jesus clashed sharply with the Pharisees because His disciples plucked grain on the Sabbath. At that time, Jesus declared, "The Son of Man is lord of the Sabbath." Following that explosive confrontation, another Sabbath arrived. Jesus entered the synagogue to teach, and a man with a withered right hand was present.
We must deeply meditate on this man’s situation. In an era where survival depended on physical labor, having a withered right hand meant more than physical inconvenience; it meant extreme destitution and the inability to earn a living. The man sat quietly in a corner of the synagogue, carrying the heavy burden of his deep pain and silent sighs.
While the text does not state why he came, one thing is certain: Jesus saw him clearly. Amidst a grand religious space, Jesus did not miss the soul suffering in the corner, untouched by the religious elite's gaze.
On the other hand, what were the scribes and the Pharisees doing?
"And the scribes and the Pharisees watched him, to see whether he would heal on the Sabbath, so that they might find a reason to accuse him."
Their eyes were not drawn to the man's suffering or tears. They were monitoring Jesus from start to finish. Their motive in watching Jesus was not to learn whether He was the Messiah sent from God, nor to learn His love and power. Their sole malicious intent was to catch Jesus breaking Sabbath regulations so they could accuse Him.
To Jesus, the disabled man was a precious soul who needed God’s mercy and the gift of true rest. But to the Pharisees, the suffering man and the healing miracle were merely tools to validate their warped legalistic judgments. They looked at the exact same scene, yet Jesus saw with "eyes of life," while the Pharisees looked with "eyes of condemnation." This is the terrifying power of confirmation bias: failing to see reality as it is, and instead distorting everything through the colored glasses of preconceived prejudices.
2) Rejecting Truth Through Silence (6:8–10)
Knowing their malicious thoughts and intentions, Jesus did not back down. He addressed the man who could not experience rest: "Come and stand here," and the man rose and stood. Then, Jesus pierced the Pharisees with a sharp question:
"I ask you, is it lawful on the Sabbath to do good or to do harm, to save life or to destroy it?"
This question was not a technical query about emergency medical procedures on a holy day. Jesus was sharply exposing that while the Pharisees prided themselves on strictly keeping Sabbath rules, they had completely missed the warm heart and intention of the God who gave the Sabbath.
Why did God give the Sabbath to His people? It was designed as a blessed day to rest exhausted bodies, experience deep fellowship with God, and show mercy to neighbors. Yet the Pharisees turned the Sabbath regulation into shackles that choked human beings. Even when a suffering person sat right before them, they blocked healing out of strict adherence to rules. Because they mistook their narrow interpretation of the Sabbath for "absolute divine law," they treated Jesus—who challenged that interpretation—as an enemy of God.
How did the Pharisees respond to this sharp question? They kept silent. Their silence was not a humble silence of repentance. It was a defensive silence, clenching their teeth in fear that their hypocrisy would be exposed before everyone. If they answered, "It is lawful to do good on the Sabbath," they would lose the grounds to stop Jesus. If they answered, "No, you must not do good on the Sabbath," they would expose the cruel, inhumane nature of their legalism. So they kept their mouths shut. And Jesus broke that stubborn silence by fully restoring the withered hand.
3) The Ending That Spiraled into Anger and Hostility (6:11)
How should witnesses of such a miraculous event respond? Since a neighbor suffering from a lifelong disability had been healed, they should have rejoiced together and praised the glory of God. Instead, they were filled with fury and plotted to accuse Jesus:
"But they were filled with fury and discussed with one another what they might do to Jesus."
Why did this happen? Because their hearts had hardened like cement against Jesus. They did not judge Jesus based on the good deeds and miracles He performed; rather, they forced every action of Jesus to fit the conclusions they had already drawn in their own minds. Consequently, even the brilliant display of Jesus' goodness unfolding right before their eyes became fuel to intensify their hostility. This is the tragic, terrifying end of confirmation bias when it corrupts our faith.
2. Five Ways Confirmation Bias Distorts Our Faith
The tragic behavior of the Pharisees is not an ancient tale from a distant land. This same confirmation bias can seep into our own hearts as believers in Christ, blinding our spiritual eyes. How does confirmation bias manifest in our faith lives?
1) It makes us "cafeteria Christians" regarding God's Word: The Bible contains comforting promises that wrap around our souls, but it also features sharp words of rebuke that expose our hidden sins and call us to repentance. When gripped by confirmation bias, we swallow only the blessings like honey, while pushing away truth that pricks our conscience, telling ourselves, "That verse is for someone else, not me."
2) It distorts our judgment and condemnation of others: If we hold a negative preconceived notion about a specific believer, pastor, or neighbor, we twist their actions no matter how pure their intentions are. We dismiss their good deeds as "hypocritical acting" while mercilessly magnifying their minor mistakes as "proof of their true character." Conversely, we endlessly excuse the grave sins of those we favor.
3) It fuels conflict and division within the church community: When trying to resolve church issues, we fail to look objectively at proposals from groups or individuals we dislike. We immediately suspect their motives: "They’re just trying to weaken our faction." Even valid critiques or words of correction are perceived not as loving advice meant to save us, but as "attacks" meant to destroy us.
4) It makes true repentance and turnaround impossible: The most beautiful moment in the life of faith is kneeling down to confess, "Lord, I was wrong; I am a sinner." However, confirmation bias prevents us from ever admitting fault. When life goes wrong, instead of looking inward, we blame circumstances, point fingers at others, and manufacture defensive arguments to justify ourselves.
5) It creates a spiritually blind state that rejects Jesus right in front of us: The Pharisees saw Jesus clearly with their physical eyes, heard the words of life with their ears, and could touch Him. Yet they failed to receive Him. It was not because of a lack of information or knowledge, but because they were trapped by their traditional rules. The true crisis of faith is not a lack of knowledge, but being trapped in old frameworks so tightly that we fail to embrace the living Truth, Jesus Christ.
3. Application and Resolution
Beloved congregation, let us turn our gaze away from the Pharisees and look into the mirror of our own hearts.
It is easy for us to point fingers at the Pharisees while reading the Bible: "How could they be so blind and furious when Jesus was performing healing miracles right before their eyes? How could they be so evil?"
Yet today, the Holy Spirit asks us quietly: "What are you looking at right now? Are you truly seeking God's will, or are you trying to validate your own stubbornness and prejudices?"
The longer we live the church life and the more experience we accumulate, the easier it is for us to slip into the seat of the Pharisee. When we encounter different theological views or styles, rather than examining whether it is a sacred opportunity to look at ourselves before God’s Word, we rush to defend our own views, condemning differing thoughts as borderline heresy.
In this moment, let us honestly ask ourselves these questions:
“Am I witnessing the life-giving work Jesus is doing in this era and in my life, or am I merely trying to confirm my pre-determined opinions and biases?”
“Am I truly listening to God's living Word, or am I cherry-picking only the verses that support my arguments?”
“Am I speaking objectively and accurately about facts, or am I distorting reality through my emotions and prejudices?”
“Am I striving to understand others from their perspective, or am I hunting for ammunition to counter and defeat them?”
The Pharisees witnessed the glorious restoration of life and yet refused to change their minds; instead, they blinded themselves to eliminate the Truth. We must use this tragic failure as a mirror for ourselves.
Furthermore, we must recognize the vast chasm between true conviction in the truth and stubborn confirmation bias:
Conviction in the truth makes us bow our knees before God’s Word, acknowledge the limits of our wisdom, and draw deeper into the embrace of Jesus every day.
Confirmation bias uses God's Word and holy truth to service our narrow judgments, condemns our neighbors, and ultimately drives us far away from the Lord.
Maturing in faith does not mean becoming someone whose opinions grow louder and who is never wrong as we age and gain titles. True spiritual maturity is the humility to willingly surrender all our thoughts, judgments, pride, and stubbornness before the Word of God and the warm heart of Jesus Christ.
May we open our hearts wide to the voice of the Holy Spirit, who lovingly breaks the stubborn prejudices we hold in our hearts through His Word. May you live a blessed life—always free in the truth, embracing your neighbors with the heart of Christ, and being continually reshaped by His Word.
Let Us Pray
Heavenly Father, we confess that like the Pharisees, we often look at life through the colored glasses of our own prejudices, selecting only what pleases us and judging others with harsh eyes. Forgive us for using Your holy Word as a weapon to justify ourselves rather than a mirror to cleanse our souls. Break our stubborn hearts of confirmation bias today. Grant us the humility to bow before Your truth, to truly see the suffering around us with Your eyes of compassion, and to live lives that walk hand in hand with the Lord of the Sabbath. In Jesus’ name, we pray. Amen.
