Why people don’t believe in God?


By BibleAsk Team

Understanding why some people choose not to believe in God is a complex issue that intertwines psychological, sociological, philosophical, and theological elements. From a biblical perspective, several key reasons can be identified. This analysis will explore these reasons, supported by references from the Bible.

1. Spiritual Blindness

One of the primary reasons the Bible cites for unbelief is spiritual blindness. This concept suggests that individuals are unable to perceive spiritual truths due to a lack of spiritual insight or a hardened heart.

  • 2 Corinthians 4:3-4: “But even if our gospel is veiled, it is veiled to those who are perishing, whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them.”

This passage indicates that Satan, referred to as “the god of this age,” blinds the minds of unbelievers, preventing them from seeing the light of the gospel, that is if they permit him to do so. This spiritual blindness keeps them from understanding and accepting the truth about God and Jesus Christ.

God gave His children ample evidence of His existence through His creative works in nature (Romans 1:20), in His written Word (2 Timothy 3:16-17), and in the life and death of Jesus Christ (John 3:16). Thus, people have every opportunity to get to know the truth and love it.

2. Hardness of Heart

The Bible frequently addresses the issue of a hardened heart as a barrier to belief in God. A hardened heart can be understood as a state of being resistant or unresponsive to God’s word and works.

  • Hebrews 3:12-13: “Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; but exhort one another daily, while it is called ‘Today,’ lest any of you be hardened through the deceitfulness of sin.”

Here, an “evil heart of unbelief” is associated with departing from God, and it warns believers to be vigilant against the hardening of their hearts through sin’s deceitfulness.

3. Influence of Worldly Wisdom

Another significant reason for unbelief is the reliance on wordly wisdom and philosophy, which often contradicts divine revelation. The Bible highlights how human wisdom can be very deceptive leading people away from the truth of God.

  • 1 Corinthians 1:18-21: “For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written: ‘I will destroy the wisdom of the wise, and bring to nothing the understanding of the prudent.’ Where is the wise? Where is the scribe? Where is the disputer of this age? Has not God made foolish the wisdom of this world? For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe.”

This passage underscores the clash between worldly wisdom and divine truth, suggesting that reliance on wordly wisdom can obstruct one’s ability to recognize and accept God.

4. Love of Sin and the World

The Bible also describes how a love for sinful practices and worldly pleasures can lead individuals to reject God. This inclination towards sin can dull spiritual awareness and make people resistant to divine truth.

  • John 3:19-20: “And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.”

People may choose to reject God because they prefer to live according to their own desires rather than adhering to God’s moral laws.

5. Pride and Self-Sufficiency

Pride and a sense of self-sufficiency can also be major hindrances to faith. When individuals believe they are autonomous and capable without God, they are less likely to seek or accept divine guidance.

  • James 4:6: “But He gives more grace. Therefore He says: ‘God resists the proud, but gives grace to the humble.'”

Pride sets people against God, making them resistant to His grace and truth. Some people reject the truth simply because they don’t want it. They don’t love Christ who is the embodiment of “the truth” (John 14:6) and don’t wish to live by His principles of goodness. They don’t desire God to interfere with their way of life.

6. Lack of Exposure to the Gospel

Some people do not believe in God simply because they have not been adequately exposed to the gospel or taught about Him in a meaningful way.

  • Romans 10:14-15: “How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written: ‘How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!'”

This passage highlights the importance of preaching and sharing the gospel to facilitate belief.

7. Skepticism and Doubt

Intellectual skepticism and doubt about religious claims and the existence of God can also lead to unbelief. The Bible acknowledges that some struggle with doubt and provides encouragement for faith.

  • John 20:27-29: “Then He said to Thomas, ‘Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.’ And Thomas answered and said to Him, ‘My Lord and my God!’ Jesus said to him, ‘Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.'”

Thomas’ doubt and subsequent belief serve as an example of how encountering evidence can transform skepticism into faith.

8. The Problem of Evil and Suffering

The existence of evil and suffering in the world is a reason why some people reject belief in God. They don’t understand that suffering is the consequences of man’s own sin. For the Creator created a perfect peaceful world without any sin. Man is responsible for the pain we see around in the world by his disobedience to God.

  • Habakkuk 1:2-3: “O Lord, how long shall I cry, and You will not hear? Even cry out to You, ‘Violence!’ and You will not save. Why do You show me iniquity, and cause me to see trouble? For plundering and violence are before me; there is strife, and contention arises.”

The prophet Habakkuk’s lament reflects the struggle to understand why God allows suffering and evil. But the truth is, it is God who is the One that suffered the most by sending His innocent to die and redeem mankind (John 3:16). This is the ultimate expression of love (John 15:13).

9. Cultural and Social Influences

Cultural and social environments can greatly influence an individual’s belief or disbelief in God. Societies that are increasingly secular or antagonistic towards religion can create environments where belief in God is less prevalent.

  • Romans 12:2: “And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.”

This verse encourages believers to resist conforming to secular cultural norms and instead to seek transformation through God’s truth.

10. Indifference and Apathy

Indifference and apathy towards spiritual matters can also lead to unbelief. When people are indifferent, they are unlikely to seek out or respond to spiritual truths.

  • Revelation 3:15-16: “I know your works, that you are neither cold nor hot. I could wish you were cold or hot. So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of My mouth.”

This passage addresses the church in Laodicea, condemning their lukewarm attitude towards faith and illustrating how apathy can lead to spiritual rejection. In addition, unbelievers don’t like their evil deeds to be exposed: “For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed” (John 3:20).

Guilty offenders hate the judges who convict them of their wrong deeds, even though it’s not the judges’ fault. Likewise, sinners hate the Lord because He convicts them of breaking His law. Sadly, those who hate the light of truth will be blinded by the devil (John 3:19). Their refusal to cherish a love for the truth makes them susceptible to being influenced by all that is not truthful “that they should believe a lie” (2 Thessalonians 2:11).

Hope for the Unbelievers

Praise God, men are not left to their own sinful nature, God wants to heal people’s hearts through His Holy Spirit that grants a new nature that hungers and thirsts after righteousness. This is a free gift from God and is available to all that ask for it (Matthew 7:7). After all what God did to save mankind, there is nothing more He can do to help them other than to respect their wishes and leave them to the course of their own choosing (Romans 1:18, 24). For in love there is no forcing (Revelation 3:20).


The reasons people don’t believe in God are multifaceted and deeply intertwined with spiritual, psychological, and social factors. According to the Bible, spiritual blindness, hardness of heart, reliance on worldly wisdom, love of sin, pride, lack of exposure to the gospel, skepticism, the problem of evil, cultural influences, and apathy all play significant roles in fostering unbelief. Understanding these reasons from a biblical perspective not only helps explain why some reject faith but also provides insight into how believers might address these issues when engaging with non-believers. By acknowledging and addressing these barriers, believers can better share their faith and offer reasons for the hope that they have.
