<The Rise in the Number of Jews Confessing Faith in Jesus>
Joseph Kwon (Editorial Board Member)
As Paul once said, the restoration of the Jewish people within God’s redemptive history over the past 2,000 years has been nothing short of a mystery. Although the early Christians, including Jesus and the twelve disciples, were predominantly Jewish, for the next two millennia, Jews were almost entirely excluded from the gospel.
During those years, the Jewish people longed for the coming of the Messiah as they looked toward the ruins of the Jerusalem Temple, living in the dilemma of being unable to offer atoning sacrifices. However, beginning in the 20th century, there has been a significant rise in the number of Jews who believe that Jesus of the 1st century fulfilled the ancient messianic prophecies recorded in the Hebrew Scriptures.
These individuals believe that Jesus rose from the dead on the third day, that through Him they have received complete forgiveness of sins, and that the new covenant foretold by the prophet Jeremiah was inaugurated through Jesus. They no longer believe that atonement can be received through sacrifices at the Temple or by offering lambs or other animals, but rather that complete salvation is available only through Jesus.
At the same time, they maintain their Jewish identity while acknowledging Jesus as the Messiah, and are therefore called Messianic Jews.
According to a recent study by LifeWay Research, there are approximately 1 million Jews worldwide who follow Jesus of Nazareth. More specifically, there are an estimated 871,000 Jewish-background believers in the United States, around 30,000 Messianic Jews in Israel, and approximately 100,000 in Europe, South America, and other regions. Considering the global Jewish population is approximately 14.8 million, this figure represents about 6.67%. Of course, within the State of Israel, the number of Jewish people is approximately 7.3 million, and among them, at most 30,000 believe in Jesus. This means that the percentage of Jews who follow Jesus is only about 0.41% of the total, indicating that the level of evangelization is extremely low.
Among the many mission-related statistics, this one stands out clearly and meaningfully, especially in light of God’s redemptive plan. It reminds us of the repeated biblical prophecy of Israel’s restoration—something that once seemed impossible.
Below are some key statistics related to the evangelization of Jews:
1. Statistics on Jewish Believers in Jesus within Israel
Statistics on Jews in Israel who believe in Jesus are generally categorized into three main sources:
Israel College of the Bible (IBC):
According to data announced by President Erez Soref in 2017, the number of Jewish Israelis who believe in Jesus had grown to approximately 30,000.
(Source: One For Israel Ministry, 2025)
Caspari Center:
Founded in 1982, this organization reported in 2020 that around 15,300 people were affiliated with Messianic congregations in Israel.
(Source: Caspari Center for Biblical and Jewish Studies, 2022)
Wikipedia and General Media:
These typically estimate between 10,000 and 20,000 Messianic Jews in Israel.
(Source: Wikipedia, Messianic Judaism, 2025)
The differences among these statistics are due to variations in methodology and scope.
Caspari Center's figures are based on publicly affiliated Messianic congregants and do not account for unreported or hidden believers. Their reports acknowledge that actual numbers may be higher due to these factors.
In contrast, Israel College of the Bible includes unofficial or private believers in a more comprehensive approach. Many Jewish believers cannot publicly express their faith due to social stigma, family opposition, or community persecution. These individuals are hard to track in official statistics, but IBC includes those connected through online platforms and media outreach.
In summary, as of 2020, around 15,300 Messianic Jews are openly affiliated with congregations, while the total, including private believers, is estimated to be around 30,000 as of 2017.
2. Statistics on Jewish Believers in Jesus Worldwide
For thousands of years, Jews have been scattered across the world in the Diaspora. Although the re-gathering began in earnest after the establishment of the State of Israel in 1948, a significant portion of the Jewish population still resides globally.
One of the clearest statistics on Jews who believe in Jesus comes from LifeWay Research, a U.S.-based evangelical organization:
LifeWay Research (mid-2020s):
(Source: LifeWay Research & Chosen People Ministries, 2020)
USA: ~871,000
Israel: ~30,000
Europe and South America: ~100,000
→ Total: ~1,000,000
However, this figure is not limited to self-identified Messianic Jews. It broadly includes all people of Jewish ancestry who hold to Christian faith.
According to the World Jewish Congress, the global Jewish population was approximately 14.8 million as of 2024. Based on this, about 6.76% of Jews are considered believers in Jesus.
(Source: World Jewish Congress, 2025)
By contrast, Messianic organizations such as the Messianic Jewish Alliance of America (MJAA), International Messianic Jewish Alliance (IMJA), Jews for Jesus, and Chosen People Ministries estimate the number of self-identified Messianic Jews worldwide to be around 300,000 to 350,000.
(Source: MJAA, 2025)
These figures are based on organizational reports, mission surveys, and internal estimates—not on official census data. They are aggregated through voluntary reporting and network-based statistics.
The discrepancy between the two sets of figures comes down to definitions and purpose:
LifeWay’s statistics include anyone of Jewish background who has made an evangelical profession of faith in Jesus. This includes Messianic Jews and Jewish-background individuals who attend general Christian churches. The scope is wide and inclusive.
MJAA/IMJA’s statistics, however, are narrower. They include only those who actively maintain a Jewish identity while believing in Jesus as Messiah. These are individuals who are members of Messianic congregations and retain Jewish traditions—such as observing biblical feasts or worshiping in Jewish-style services. Their criteria are more conservative and identity-focused.
Also, due to the history of Christian anti-Semitism, many Messianic Jewish communities avoid the term church and prefer congregation. This reflects a conscious effort to retain Jewish identity and distinguish themselves from mainstream Christianity.
Thus, the different purposes behind the data explain the variation:
LifeWay's evangelical statistics aim to understand the broader scope of Jewish evangelism, while MJAA and IMJA seek to track the growth of Messianic Jewish communities specifically.
3. Trends in the Number of Jewish Believers in Jesus Over the Past 2,000 Years
Although there are no precise statistics available for this topic, we can gain a general understanding through historical sources.
In the 1st century, the disciples of Jesus and the early church represented a time when Jewish believers in Christ were central. The early church, including Jesus and His disciples, was composed entirely of Jews. After Jesus’ ascension, thousands of Jews came to believe in Him as the Messiah, and the Jewish followers of Jesus were seen as a Messianic movement within Judaism, centered around the church in Jerusalem.
From the 2nd to 4th centuries, a separation between Judaism and Christianity began. Although the historical context is complex, we will not go into detail here. Essentially, Jewish leaders declared Jews who believed in Jesus as heretics and expelled them from the community. At the same time, Hellenized, Gentile-dominated churches grew in influence, reducing the impact of Jewish believers within the Christian community.
Around the time of the Council of Nicaea (325 AD), Sunday laws were established (replacing Saturday, the Jewish Sabbath, with Sunday for worship), and as Christianity became the state religion of the Roman Empire, Jewish Christians were marginalized for continuing to observe the Sabbath. The Jewish community, emphasizing religious purity, also rejected them. Thus, Jewish Christians became marginalized by both sides and rapidly declined in number.
In 321 AD, Emperor Constantine declared, “On the venerable Day of the Sun (dies Solis), let the magistrates and people residing in cities rest, and let all workshops be closed.” This not only marked a shift that would lead Christianity into the spiritual darkness of the Middle Ages but also contributed to the near extinction of Jewish believers in Jesus.
(McGuckin, J. A., 2004)
During this period, early church fathers made anti-Jewish theological statements that deeply influenced later church history. Messianic Jews today regard this period as highly significant. From this historical perspective, Messianic Jews believe that the alliance between Rome (a secular state) and Christianity led to a distortion of the Bible’s essence. This became a foundational moment distinguishing general Christianity from Messianic Jewish identity.
(Moss, C. R., 2012)
As a result, Jewish-background Christians refer to this era as the “Parting of the Ways”—the complete separation between Christianity and Judaism. Jewish believers in Jesus virtually disappeared.
Throughout the Middle Ages (up to the 16th century), some Jewish converts to Christianity existed in Europe (known as Conversos or Marranos), but most of these conversions were forced or done merely for survival. Due to intense antisemitism, medieval churches distrusted or persecuted Jewish converts. During this period, the public identity of a Jewish believer in Jesus was virtually impossible, and there are very few historical records of such individuals.
(Roth, C., 2005)
From the 17th to 19th centuries, a new era of Christian missions began. As the church emerged from centuries of spiritual darkness and began to recover its understanding of God's will, spiritual revival and global missions were launched. The restoration of the Jewish people was also part of this wider spiritual awakening. Evangelical mission movements targeting the Jewish people arose in Germany, the UK, Scandinavia, and the United States. Gentile Christians, having rediscovered the power of the gospel, began sharing the message in Jesus' way, leading to the sincere conversion of some Jews. These converts often served as missionaries, Bible translators, or seminary teachers. Notable figures include Joseph Frey and Alfred Edersheim.
As a result of these efforts, by the late 19th century, it is estimated that there were about 20,000 to 30,000 Jewish believers in Jesus worldwide. In the early 20th century, the number of Jews in Europe who had accepted Jesus as the Messiah surged to over 230,000—a shift unprecedented in the previous 1,800 years.
(Becker, A., 2017)
However, this revival was largely destroyed during the two World Wars and the Holocaust. While the Nazis, who sought the extermination of the Jews, cannot be considered true Christians, it is nonetheless true that 85% of Germans at the time identified as Christians and many supported the Nazi regime.
Tragically, even the Jewish people who had returned to Jesus after 1,800 years were killed by those who called themselves Christians. This historical irony underscores how Christians, when focused solely on their own safety and national prosperity, can act in ways that completely contradict God’s will.
By the 1930s and 1940s, the number of Jewish believers reached historic lows. By 1945, only 5,000 to 10,000 Jewish believers were estimated to exist worldwide.
(Becker, A., 2017)
In 1967, the Six-Day War and the transfer of control over Jerusalem from Jordan to Israel marked a dramatic turning point. Around the same time, the Jesus Movement (or Jesus Revolution) began in the United States, greatly impacting secular American Jews. Tens of millions of previously irreligious Americans came to faith in Jesus, and many experienced spiritual rebirth. On June 21, 1971, this movement became so widespread that Time Magazine featured it as a cover story.
(Mohs, M., 1971)
From this time on, many American Jews began to believe in Jesus, and the identity of Messianic Jews began to be restored among them. Organizations such as the Messianic Jewish Alliance of America (MJAA), Jews for Jesus, and Chosen People Ministries were founded, and evangelism efforts spread across the U.S. From there, Messianic Jewish congregations began to be established in Russia, Ukraine, Israel, South America, Europe, and beyond.
As noted earlier, according to LifeWay Research (mid-2020s), approximately 1 million out of the world’s 15 million Jews believe in Jesus today. In all of history, there has never been such a dramatic increase in Jewish believers as what we are now witnessing. From a redemptive-historical and missiological perspective, this trend is theologically and strategically significant for both the modern State of Israel and the global church.
4. Ultimately, History Progresses According to God’s Word
Statistical data is not needed to prove that God’s Word is true. But unbelieving humans demand signs and evidence—and only when these are present do they begin to believe and obey God. Those who understand this human nature try to persuade others using various tools and wisdom.
But those whom God uses to carry out His redemptive work have always been people of faith—those who believe without seeing. Circumstances change, and with them, statistics and numbers change as well. People who move according to these variables are easily swayed by trends, popular opinions, or mass psychology.
However, only the Word of God remains unchanged. And God’s work has always progressed through those who believe and follow His Word.
The same principle applies to missions to Israel. In the 17th century, a few believers, who trusted in the power of the gospel, looked at the Jews—who had been wounded by centuries of exclusion from the gospel and persecution by medieval Christianity—and began sharing the gospel in the way Jesus did. The Jewish population in Europe was not unreached due to a lack of opportunity; rather, deep-seated antisemitism and anti-Christian ideology within rabbinic Judaism made evangelism nearly impossible. Even today, many Jews are hostile or completely opposed to reading the New Testament.
Nevertheless, these faithful witnesses sowed the seeds of the gospel by faith in the face of impossible odds.
Through the Jesus Movement of the 1960s, many reborn Christians boldly proclaimed the gospel. And surprisingly, even Jews who had suffered through the Holocaust began to come to faith in Jesus.
Similarly, after the Second Intifada in 2005, there was a rapid increase in Jewish believers in Israel. This, too, was the fruit of faithful witnesses who believed in and proclaimed the power of the gospel.
All of this was accomplished by those who trusted God’s Word even when nothing visible seemed to confirm it.
And the ultimate goal of missions to Israel is not merely the return of the Jewish people to God. It is the restoration of the original calling for which God first chose Israel: that they would rise as a light to the nations, proclaiming God’s salvation—namely, Jesus—to the world.
Currently, it may seem impossible for the Jewish people to fulfill the Great Commission, especially given the geopolitical situation and the deep hostility toward the gospel within Israeli society. Many Jews still strongly oppose Jesus and His message.
So although many people are familiar with Isaiah 49:6 (“I will make you a light to the Gentiles, that you may bring my salvation to the ends of the earth”), few actually believe it and act accordingly. Yet, throughout history, God’s work has always been fulfilled through people who trust in His Word—and this seemingly impossible prophecy will also ultimately be fulfilled.
