Speaking in tongues is important in the Bible because it demonstrates the Holy Spirit’s work, signals the inclusion of people from different nations, and serves as a spiritual gift for the church. Yet Scripture does not present tongues as the universal evidence of salvation or spiritual maturity. Its meaning and purpose must be understood through the different contexts in Acts and 1 Corinthians, especially Paul’s teaching about love, interpretation, and order.
The Importance of Speaking in Tongues in the Bible
Tongues Show That the Gospel Is for Every Nation
The first major biblical account of speaking in tongues occurs at Pentecost in Acts 2. When the Holy Spirit came upon the disciples, they began speaking in languages they had not learned. Jews from many regions heard the disciples declaring “the mighty works of God” in their own languages (Acts 2:1–11).
This event demonstrated that the gospel was not limited to one ethnic group or language. Jesus had commanded His followers to be witnesses “to the end of the earth” (Acts 1:8), and Pentecost showed that God was beginning to fulfill that mission. The Spirit enabled the disciples to communicate across linguistic boundaries so that people from many nations could hear the message of Christ.
Some interpreters also see Pentecost as a theological contrast with Babel in Genesis 11. At Babel, human pride was associated with the confusion of languages; at Pentecost, God used many languages to announce salvation. Acts 2 does not explicitly call Pentecost a reversal of Babel, but the contrast helps explain the event’s significance: God was gathering people from different nations into one people through Christ without erasing their distinctions.
The same pattern appears in later episodes:
- In Acts 10, Gentiles in the household of Cornelius spoke in tongues and praised God. This convinced Jewish believers that the Holy Spirit had been given to Gentiles as well.
- In Acts 19, disciples in Ephesus spoke in tongues and prophesied after receiving the Holy Spirit.
- In each case, tongues were connected with the Spirit’s work and helped confirm that God was extending the gospel beyond its original Jewish setting.
Tongues therefore had redemptive-historical importance. They testified that God was forming one church from many peoples.
Tongues Serve as a Sign of the Spirit’s Work
Speaking in tongues is repeatedly associated with the presence and activity of the Holy Spirit. In Acts, it accompanies significant moments in which people receive the gospel and become part of the expanding Christian community.
Paul also calls tongues a “sign” in 1 Corinthians 14:22. This statement requires careful interpretation. Paul is not saying that tongues automatically convince every unbeliever to believe. In the same chapter, he warns that uninterpreted speech in a gathering may cause outsiders to think the church is confused (1 Corinthians 14:23). His reference to Isaiah 28 suggests that tongues can function as a sign of God’s judgment when people hear speech they do not understand yet remain unwilling to listen.
The importance of tongues as a sign, then, depends on the setting and purpose. In Acts, tongues marked decisive movements of the Spirit’s mission. In Corinth, however, the gift was being used in ways that created confusion and competition. A genuine spiritual gift could be misused when separated from love and concern for others.
The Bible also does not teach that every Christian must speak in tongues. Paul asks, “Do all speak with tongues?” in 1 Corinthians 12:30, and the expected answer is no. The Spirit distributes gifts according to His will (1 Corinthians 12:11). All believers are baptized by one Spirit into one body (1 Corinthians 12:13), but they do not all receive the same gift.
Tongues Edify the Speaker and the Church
Paul distinguishes between the personal and congregational dimensions of tongues. “The one who speaks in a tongue speaks not to men but to God,” because no one understands him without interpretation (1 Corinthians 14:2). Paul also says that the person who speaks in a tongue “builds himself up,” while the person who prophesies builds up the church (1 Corinthians 14:4).
This does not mean that personal spiritual strengthening is wrong. Paul himself says, “I want you all to speak in tongues,” but he places greater value on prophecy in a gathered church because prophecy communicates understandable truth to others (1 Corinthians 14:5). His concern is not whether tongues are genuine but whether their use benefits the congregation.
For public worship, interpretation is essential. An interpreted tongue can strengthen the church because its meaning becomes accessible to everyone. Without interpretation, the speaker should remain silent in the congregation and speak privately to God (1 Corinthians 14:27–28).
This principle explains why the biblical gift should not be evaluated only by whether a person experiences something spiritually intense. The relevant question is also whether the gift serves God and benefits other believers. Spiritual activity becomes edifying when it communicates truth, encourages faith, and strengthens the body of Christ.
The expression “tongues of angels” in 1 Corinthians 13:1 is sometimes used to support the idea of a heavenly prayer language. However, Paul’s statement occurs within a series of deliberately elevated examples: speaking in human and angelic languages, understanding mysteries, possessing extraordinary faith, and giving away everything. The passage’s central point is that even remarkable spiritual experiences are worthless without love. It should not be used by itself to establish a doctrine that all believers should possess a distinct angelic language.
Tongues Must Be Governed by Love and Order
The most sustained teaching about tongues appears in 1 Corinthians 12–14. Paul places the gift within the wider work of the Holy Spirit, alongside wisdom, knowledge, healing, prophecy, discernment, and other gifts. No gift makes one Christian more valuable than another, because the church is one body with many members (1 Corinthians 12:12–27).
First Corinthians 13 provides the necessary framework. Love is more important than any spiritual gift. A person may speak in human or angelic languages, possess great knowledge, or demonstrate extraordinary faith, yet remain spiritually deficient if he does not love others.
Paul then applies this principle to gathered worship:
- Tongues should be used for the good of the church.
- Public tongues should be interpreted.
- Only a limited number should speak in a service.
- Speakers should take turns rather than speak over one another.
- The congregation should be able to understand what is said.
- If no interpretation is available, the speaker should remain silent publicly.
- Everything should be done “decently and in order” (1 Corinthians 14:40).
Paul’s conclusion is balanced: “Do not forbid speaking in tongues,” but also “let all things be done for building up” (1 Corinthians 14:39, 26). The Bible therefore rejects two opposite errors: treating tongues as proof of superior spirituality and suppressing a biblical gift merely because it has sometimes been misused.
What Speaking in Tongues Means in Acts and Corinth
The Languages at Pentecost
In Acts 2, the disciples speak languages recognized by the international crowd. Luke lists people from regions including Parthia, Media, Egypt, Rome, Crete, and Arabia, and each group hears the message in its own language.
This is the clearest biblical example of tongues as recognizable human languages given by the Spirit. The miracle is not merely that the disciples speak; it is that people from different linguistic backgrounds understand the proclamation of God’s works.
The Congregational Gift in Corinth
The situation in Corinth is different in emphasis. Paul describes speech that requires interpretation because the gathered congregation cannot understand it naturally (1 Corinthians 14:2, 5, 13). The text does not settle every modern question about whether these tongues were always human languages, spiritual speech, or a category that could include more than one expression. It does make the practical requirement unmistakable: public speech must be interpreted if it is to serve the church.
The difference between Acts 2 and 1 Corinthians does not require two unrelated gifts. The same Spirit may give the ability to speak in languages for missionary proclamation in one context and provide a message requiring interpretation in another. The purpose and setting determine how the gift should be used.
What the Bible Does Not Teach About Tongues
Several conclusions commonly associated with tongues go beyond what Scripture says.
Tongues are not presented as the universal proof of conversion. The New Testament teaches that people become Christians through faith in Christ and the work of the Spirit, not through possession of one particular gift. The Spirit gives different gifts to different believers.
Tongues are not a measure of spiritual rank. Paul places tongues among the gifts of the body, but he does not rank people according to whether they possess them. Love, holiness, obedience, and service are better indicators of Christian maturity than dramatic spiritual experiences.
Tongues do not make interpretation unnecessary. Even if a person believes a message is genuinely from the Spirit, Paul’s instructions still apply in public worship. The congregation must be able to understand and benefit from what is spoken.
Acts does not provide a mechanical formula for receiving the Spirit. Tongues occur in several significant episodes, but not every conversion account in Acts mentions them. For example, Acts 8 describes the Samaritans receiving the Holy Spirit without explicitly saying that they spoke in tongues. Biblical narratives should not be turned into a requirement that the text itself does not impose.
How Christians Interpret Tongues Today
Christian traditions disagree about whether the miraculous gifts described in the New Testament continue in the same form today.
Continuationists believe that tongues, prophecy, healing, and other gifts remain available to the church until Christ returns. They generally appeal to passages such as 1 Corinthians 12–14 and argue that Paul regulates tongues rather than predicts their disappearance.
Cessationists believe that some revelatory or sign gifts had a foundational role in the apostolic era and are not ordinarily given in the same way today. They often connect these gifts with the apostles’ unique role in establishing the church and delivering authoritative revelation.
Other Christians hold positions between these views, affirming that God may act in extraordinary ways while remaining cautious about claims made in the name of spiritual gifts.
These interpretations differ, but several biblical principles remain clear across the debate:
- No Christian should be pressured to claim a gift he or she does not possess.
- No gift should be used to create spiritual superiority or division.
- Public use must be understandable and orderly.
- Every spiritual experience must be evaluated by Scripture and by its fruit.
- Love for God and neighbor is more fundamental than any particular manifestation.
Why Speaking in Tongues Matters Biblically
Speaking in tongues matters because it reveals several central truths about the church and the work of the Holy Spirit. God communicates across human boundaries, welcomes people from every nation, equips believers in different ways, and calls the church to use spiritual gifts for mutual strengthening rather than personal status.
Its significance is therefore greater than the question of whether a particular Christian has spoken in tongues. The broader biblical message is that the Spirit sovereignly gives gifts, Christ unites diverse people into one body, and genuine spirituality is governed by love and directed toward the good of others. Tongues have a legitimate place in the biblical account, but they must remain within that larger framework.
