What Is Unbelief In The Bible?

Unbelief is a lack of faith or trust in God that is mentioned numerous times throughout the Bible. If you’re short on time, here’s a quick answer: unbelief refers to doubting or rejecting God’s word, his promises, his commands and his existence.

In this comprehensive article, we will examine the meaning of unbelief according to the Bible, analyze key examples of unbelief described in Scripture, understand why unbelief is dangerous from a biblical perspective, and learn what the Bible teaches about overcoming unbelief and growing in faith.

Defining Unbelief Biblically

Lacking Faith in God

Unbelief is often characterized by a lack of faith or trust in God. This can manifest in different ways. Some people may doubt God’s existence, goodness, or power. Others may intellectually believe in God but fail to rely on Him in their daily lives.

According to the Bible, having faith in God begins with believing that He exists and rewards those who earnestly seek Him (Hebrews 11:6). True faith involves trusting in God’s character and depending on Him even when circumstances seem impossible or unclear.

Unbelief stems from not fully trusting who God says He is and what He promises to do.

Doubting God’s Word and Promises

Closely related to lacking faith, unbelief can also be seen as doubting or questioning God’s revealed truth in Scripture. Though honest inquiries about the Bible are understandable for those seeking God, continual skepticism of clear biblical teaching indicates a heart inclined toward unbelief.

Jesus rebuked those who doubted (Matthew 14:31) and warned of dire consequences for hardening one’s heart to God’s Word (Mark 16:14). Scripture exhorts believers not to be like faithless Israelites who rebelled against God in the wilderness due to unbelief (Hebrews 3:12-19).

God is not pleased when people distrust His word and promises despite past evidence of His faithfulness. Persistent uncertainty regarding biblical truth demonstrates an unbelieving heart.

Rejecting God’s Commands and Instructions

The most blatant form of unbelief is the outright rejection of God’s clear commands and instructions. Unbelief at its core refuses to recognize God’s authority and submit to Him. Though unbelievers may claim intellectual assent to God’s existence, their willful disobedience exposes the true condition of their hearts.

Jesus upbraided the Pharisees for nullifying God’s Word with manmade rules and traditions (Mark 7:1-13). Blatant rejection of biblical commands shows an unbelieving and rebellious spirit. According to 1 Samuel 15:23, “rebellion is as the sin of divination, and presumption is as iniquity and idolatry.”

Though Christians may struggle with periodic doubt or lapses in obedience, wholesale rejection of God’s rightful authority contradicts genuine saving faith.

Examples of Unbelief in the Bible

Throughout the Bible, there are numerous examples of people displaying unbelief towards God and His promises. Unbelief is essentially a lack of faith – not trusting in God’s character and doubting His ability or willingness to act.

This grieves the heart of God, who deeply loves His people and has demonstrated that love in countless ways. Let’s explore some noteworthy biblical examples of unbelief.

The Israelites in the Wilderness

After God miraculously delivered the Israelites from slavery in Egypt through awe-inspiring signs and wonders, they struggled with unbelief during their wilderness wanderings. Though they saw God provide for them daily with manna and quail, they grumbled and questioned whether He was able to adequately provide for their needs (Exodus 16).

Their unbelief reached a climax when the 12 spies returned from Canaan. Despite God’s promise to give them the land, 10 spies gave a negative report, amplifying the difficulties and stirring the people’s fears and complaints (Numbers 13-14).

As a result of their unbelief, that unbelieving generation was forbidden to enter the Promised Land.


When the angel Gabriel appeared to the priest Zacharias to proclaim that his elderly, barren wife Elizabeth would bear a son (John the Baptist), Zacharias responded in unbelief at this good news, doubting God’s ability to overcome their natural limitations.

Gabriel rebuked Zacharias for his unbelief, declaring “For behold, you shall be silent and unable to speak until the day when these things take place, because you did not believe my words” (Luke 1:20).

Zacharias lost his voice until his son was born, a sobering reminder that unbelief hinders our capacity to testify of God’s goodness.

The Disciples in the Storm

While crossing the Sea of Galilee by boat with Jesus, a great storm arose and the disciples feared for their lives. Despite having Jesus – the Son of God – with them in the boat, they responded in unbelief that He didn’t care if they perished (Mark 4:35-41).

Jesus rebuked them for being “afraid” and having “no faith”, then He calmed the storm. Even those closest to Jesus were prone to forget His power and allow fear and unbelief to overwhelm them in the storms of life.

These examples remind us that unbelief is a grievous sin that limits God’s ability to work in our lives. Yet despite our fickle faith, God remains forever faithful to His promises. By His grace, may we nurture steadfast belief in His loving care and mighty saving power.

Dangers of Unbelief According to Scripture

The Bible warns that unbelief can have serious consequences. Here are some of the main dangers of unbelief that Scripture points to:

1. Missing out on God’s blessings and promises

God has made many great promises in the Bible to those who believe in Him, such as forgiveness, guidance, comfort, and eternal life. However, those who persist in unbelief will fail to receive these blessings.

As Hebrews 3:19 states, “So we see that they were not able to enter, because of their unbelief.”

2. Spiritual blindness and deception

Unbelief can lead to spiritual blindness, causing people to be deceived by false teachings or worldly philosophies that contradict God’s truth. As 2 Corinthians 4:4 says, “The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ.”

3. Hardened hearts and stubborn wills

Choosing unbelief over and over can make people’s hearts calloused and stubbornly self-willed against God’s ways. Romans 2:5 warns, “But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God’s wrath.”

4. Judgment and condemnation

Perhaps most seriously, Scripture makes clear that those who reject Christ through unbelief will face eternal judgment and separation from God. As John 3:18 solemnly declares, “Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.”

Overcoming Unbelief Through Faith in Christ

Unbelief is a major obstacle that can prevent people from fully embracing the salvation offered through faith in Jesus Christ. However, through God’s grace and the transformative power of the Holy Spirit, unbelief can be overcome.

Here are some key ways that faith in Christ enables people to move past unbelief into a life transformed by the gospel.

Recognizing the Limitations of Human Understanding

A significant source of unbelief is the assumption that we can rely entirely on human reason and intellect to understand all truth. However, God’s ways are higher than ours (Isaiah 55:9). Submitting our limited human understanding to the infinite knowledge and wisdom of God is an important step of faith that opens our hearts to receive greater revelation and insight.

Seeking Spiritual Understanding from God

While human intellect has value, true wisdom comes from God (Proverbs 2:6). Believers must humbly ask God for spiritual understanding and the discernment to separate truth from deception (James 1:5). As we seek God with sincerity, He will lead us to greater faith.

Focusing on the Convicting Work of the Holy Spirit

Jesus said the Holy Spirit would convict people of sin and righteousness (John 16:8). As we focus on the inner work of the Spirit, He enlightens our minds and instills confidence in God’s truth. Experiencing the Spirit’s ministry helps overcome doubt and skepticism.

Understanding the Difference Between Fact and Faith

Some expect empirical evidence for all truth claims, but faith requires trust in the unseen (Hebrews 11:1). While we should thoughtfully examine reasons for faith, demanding scientific proof for spiritual matters is misguided. Discerning the difference between human facts and godly faith aids belief.

Associating with Faith-Filled People

Spending time with strong believers reinforces our own faith. Their firsthand testimonies, spiritual wisdom, and modeling of godly lives inspires greater confidence in Christ. Faith is strengthened in community (Romans 1:12).

Trusting in the Promises of God

Standing on the unchanging promises of Scripture counteracts doubt fueled by changing circumstances. Recalling God’s faithfulness in our lives and in the lives of others fosters steadfast assurance regardless of obstacles. His guarantees never fail (2 Corinthians 1:20).

While overcoming deeply rooted unbelief is challenging, God’s amazing grace is sufficient. As we humbly surrender our lives to Jesus and engage in faithful spiritual practices, the miracle of transformed belief becomes a reality. Faith opens the door to living fully in the freedom of God’s love.


In conclusion, unbelief is characterized in the Bible as a lack of faith and trust in God, his word, his promises, his power, and his existence. Scripture contains many examples of unbelief and warns of its spiritual dangers.

Yet the Bible also provides the solution to overcoming unbelief through placing one’s faith in Jesus Christ and allowing the Holy Spirit to produce faith and spiritual fruit in the believer’s life.
