Where in the Bible does it mention not everyone will believe?

The Bible is replete with passages that address the reality that not everyone will come to believe in the message of the Gospel. This theme is woven throughout both the Old and New Testaments, underscoring the persistent human tendency to resist divine truth and the sovereignty of God in the matter of belief. As we explore these scriptures, we will see a consistent message: despite the universal offer of salvation through Jesus Christ, not everyone will accept it.

One of the most explicit references to this reality is found in the teachings of Jesus Himself. In the Gospel of Matthew, Jesus tells the Parable of the Sower (Matthew 13:1-23). In this parable, Jesus describes a sower who scatters seeds on different types of soil, each representing different responses to the Word of God. Some seeds fall on the path and are eaten by birds, others fall on rocky ground and wither because they have no root, some fall among thorns and are choked, but some fall on good soil and produce a bountiful harvest. Jesus explains that the seed represents the Word of God, and the various soils represent the different ways people receive it. This parable highlights that not everyone who hears the Gospel will believe and bear fruit.

Jesus further elaborates on this in Matthew 7:13-14, where He says, "Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few." This passage starkly contrasts the broad path that many follow, which leads to destruction, with the narrow path that few find, which leads to life. It emphasizes the sobering truth that the majority of people will not choose the path of faith.

The Apostle Paul also addresses the issue of unbelief in his letters. In Romans 10:16, Paul laments, "But not all the Israelites accepted the good news. For Isaiah says, 'Lord, who has believed our message?'" Here, Paul is quoting Isaiah 53:1, which underscores the historical reality that even among God's chosen people, there was widespread unbelief. Paul further explores this theme in Romans 11:7-8, stating, "What then? Israel failed to obtain what it was seeking. The elect obtained it, but the rest were hardened, as it is written, 'God gave them a spirit of stupor, eyes that would not see and ears that would not hear, down to this very day.'"

In John 12:37-40, the Apostle John provides a poignant commentary on the unbelief of the people despite Jesus' miraculous signs: "Even after Jesus had performed so many signs in their presence, they still would not believe in him. This was to fulfill the word of Isaiah the prophet: 'Lord, who has believed our message and to whom has the arm of the Lord been revealed?' For this reason they could not believe, because, as Isaiah says elsewhere: 'He has blinded their eyes and hardened their hearts, so they can neither see with their eyes, nor understand with their hearts, nor turn—and I would heal them.'"

These passages collectively illustrate a profound theological concept: the interplay between divine sovereignty and human responsibility. While the Gospel is freely offered to all, the Bible acknowledges that belief is ultimately a gift from God. Ephesians 2:8-9 states, "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast." This underscores that faith itself is a divine gift, and not everyone will receive it.

Moreover, the Bible speaks to the reality of spiritual blindness and hardness of heart, which prevent many from coming to faith. 2 Corinthians 4:3-4 says, "And even if our gospel is veiled, it is veiled to those who are perishing. 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, who is the image of God." This passage attributes unbelief to the blinding influence of Satan, the "god of this age," who actively works to obscure the truth of the Gospel.

Additionally, Jesus Himself acknowledges the difficulty of belief in John 6:44, saying, "No one can come to me unless the Father who sent me draws them, and I will raise them up at the last day." This statement highlights the necessity of divine intervention for someone to come to faith. It is not merely a matter of human decision but requires the drawing power of the Father.

The concept of a remnant—a small, faithful group within a larger unfaithful population—is another biblical theme that underscores the reality that not everyone will believe. In Romans 11:5, Paul writes, "So too, at the present time there is a remnant chosen by grace." This idea of a remnant is rooted in the Old Testament, where prophets like Isaiah and Elijah speak of a faithful few who remain true to God amid widespread apostasy (Isaiah 10:20-22; 1 Kings 19:18).

C.S. Lewis, in his book "Mere Christianity," touches on the mystery of belief and unbelief. He writes, "When you are arguing against Him you are arguing against the very power that makes you able to argue at all: it is like cutting off the branch you are sitting on." This analogy captures the paradox of human resistance to God, even as we are sustained by His very power.

In summary, the Bible clearly teaches that not everyone will believe in the Gospel. This is evident in the teachings of Jesus, the writings of Paul, and the broader narrative of Scripture. The reasons for unbelief are multifaceted, including spiritual blindness, hardness of heart, and the necessity of divine intervention for someone to come to faith. This reality calls believers to a posture of humility and reliance on God's grace, as well as a commitment to faithfully proclaim the Gospel, trusting that God will draw those He has chosen to Himself.
