The Bible: A Sin To Not Believe?

The Bible contains many passages that suggest a person's failure to believe in God is a sin. In John 16:9, the Bible states that the world's sin is that it refuses to believe in me. This idea is echoed in other verses, such as whoever does not believe will be condemned and whoever believes in the Son of God has this testimony within him; whoever does not believe God has made Him out to be a liar. The consequences of unbelief are also mentioned, with one verse stating that through the door of unbelief is standing in front of the Judge with no Advocate, spiritual death, and eternal separation from God. However, it is important to note that the concept of unbelief as a sin is a complex and highly debated topic, with some arguing that it should not be considered a sin in the modern world.

Unbelief is a sin because it reveals an evil heart

The idea that unbelief stems from an evil heart may be difficult to reconcile with modern cultural attitudes. In contemporary Western society, unbelief is often viewed as a neutral or even positive trait. We may admire those who do not believe as being sharp-minded or thoughtful. However, it is important to recognise that unbelief is not merely a matter of intellectual doubt. Instead, it arises from a "hardness of heart" and self-protection.

The Bible makes it clear that belief is crucial to our relationship with God. In the Gospel of John, unbelief is described as the root cause of sin, as it represents a failure to trust in God and accept Jesus as the Messiah. This is further emphasised in Romans 14:23, which states that "whatever is not from faith is sin". Here, the apostle Paul highlights the importance of faith as the foundation of our actions and attitudes.

Jesus himself took a strong stance against unbelief, rebuking those who did not believe and emphasising the seriousness of the issue. He understood the high stakes involved, as it is only through belief that we can experience salvation and eternal life with God. By contrast, unbelief leads to spiritual death and eternal separation from God.

In conclusion, while the idea that unbelief is a sin may be challenging, it is supported by Biblical teachings that emphasise the centrality of faith in our relationship with God. Unbelief is not simply a neutral characteristic but rather a reflection of an evil heart, marked by a lack of trust in God and a rejection of His truth.

Jesus doesn't confuse unbelief with doubt

> "The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel." (Mk 1:15)

Belief and unbelief are not neutral for Jesus. He calls us to belief and frequently rebukes unbelief. However, he also responds to the sincere doubt of Thomas with great patience. David had seasons where he was racked by doubt. Peter doubted Christ, then denied him once, twice, thrice, and yet was still restored.

Jesus distinguishes between doubt and unbelief. Doubt may sprout from the soil of faith. This is not unbelief. This form of doubt can, in fact, be healthy in stretching one's faith and relationship with God.

Unbelief, on the other hand, is a deliberate decision to live life as if there is no God. It stems from a hardness of heart and self-protection, rather than mere intellectual doubt.

Examples of Jesus' Response to Doubt

The Father of a Demon-Possessed Boy

In Mark 9, the father of a demon-possessed boy cries out to Jesus:

> "I believe! Help my unbelief!"

Jesus doesn't scold the father for his doubt, nor chastise him for not being able to fully believe in his ability to heal his son. Instead, he rewards the man for his honesty and heals the boy.

John the Baptist

John the Baptist baptised Jesus, and when he did, the Spirit of God descended on Christ, and the audible voice of God the Father said, "This is my Son." Yet, at the end of his life, John himself had doubts about who Jesus was. When he was in prison, John sent his disciples to ask Christ if he was the Messiah or if they should be looking for another. After hearing the audible voice of God from the sky, John the Baptist still doubted.

The Disciples

In Matthew 28:16-17, the eleven disciples went to Galilee, to the mountain where Jesus had told them to go. When they saw him, they worshipped him; but some doubted.

These eleven men had spent about three years with Jesus. They'd seen miracles happen. Their Messiah was crucified and buried, and a couple of days later, they were dining with him. If there was ever a good reason to believe in the unbelievable, the disciples had experienced it.

And yet, here they were with their previously deceased King, and some of them were still harbouring doubts. What kind of doubts? The text doesn't tell us. But Jesus doesn't chastise them. He doesn't tell them that he was going to give them critical information but since they still don't fully believe, he won't. Instead, he meets them where they are. He confides in them and charges them with their new responsibilities.

The Difference Between Doubt and Unbelief

Doubt is a natural part of the Christian experience and can be the avenue God chooses to use to draw us closer to himself. Doubt and faith can coexist in someone's life at the same time.

However, just as sin can creep in during moments of temptation, unbelief can be born amid doubt. An intentional celebration of doubt can quickly backslide into a glorification of it, so it's crucial to approach doubts with discernment. It's easy for doubt to lead to unbelief if we obsess over it.

Unbelief is not a neutral characteristic

The Bible states that "whoever does not believe will be condemned" and that "the world's sin is that it refuses to believe". Jesus himself frequently rebuked unbelief, saying, "If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things?" and expressing marvel and dismay at the unbelief he encountered.

The high stakes of belief and unbelief are often cited as the reason for Jesus' harsh stance against unbelief. Belief in Jesus Christ is seen as the path to salvation, adoption, and eternal life with God, while unbelief leads to spiritual death and eternal separation from God. The consequences of unbelief are serious, and Jesus' strong reactions to it stem from the gravity of the sin.

Furthermore, unbelief is viewed as more than just intellectual doubt. It is associated with a "hardness of heart" and self-protection, indicating a deeper issue than mere skepticism. Unbelief is considered a serious sin, and Christians are encouraged not to take it lightly, either in themselves or in others.

Unbelief insults God's integrity

The Bible is clear that unbelief is a sin. In John 16:9, it is stated that the world's sin is that "it refuses to believe" in Jesus. This is further supported by other verses in the Bible, such as Romans 14:23, which states that "whatever is not from faith is sin".

Unbelief is a serious sin because it stems from a hardness of heart and self-protection, revealing an evil heart. It is an insult to God's integrity, robbing Him of His honor. The Bible says in Hebrews 11:6 that "without faith it is impossible to please God". Unbelief goes against the very nature of God, who is infinitely wise, honorable, and dependable.

The consequences of unbelief are eternal and severe. Through the door of unbelief is standing before the Judge with no Advocate, spiritual death, and eternal separation from God. Jesus emphasizes the seriousness of unbelief by rebuking those who do not believe. He understands the high stakes involved and knows that only through belief can we experience the transforming power of new birth and God's rescue.

Furthermore, unbelief is not a neutral characteristic. It is not merely intellectual doubt, but an active rejection of the truth revealed in Christ. Jesus calls us to belief and frequently addresses unbelief during His ministry.

In conclusion, unbelief is a sin that insults God's integrity. It stems from an evil heart and has severe consequences. Jesus harshly addresses unbelief because He understands the high stakes involved and wants us to experience the salvation, adoption, and life together with God that comes through belief in Him.

Unbelief is not the same as intellectual doubt

Unbelief, on the other hand, stems from a hardness of heart and self-protection. It is an active rejection of the truth revealed in Christ. In the Gospel of John, belief is not just intellectual assent but a deep, personal trust in Jesus Christ. The failure to believe in Jesus is the ultimate sin because it rejects the only means of salvation and reconciliation with God.

The consequences of unbelief are serious. Through the door of unbelief is standing before the Judge with no Advocate, spiritual death, and eternal separation from God. Jesus is harsh against unbelief because the stakes are so high. It is only through belief that we can experience the transforming power of new birth, salvation, and life with God.

Therefore, we must weigh our unbelief, as eternity is at stake. Unbelief is a serious sin, and we ought not to take it lightly, either in ourselves or in others.
