What Does the Bible Say About Speaking in Tongues?

The Bible speaks about tongues in two main places: the day of Pentecost in Acts 2, and Paul’s long discussion in 1 Corinthians 12–14. On Pentecost, the Spirit filled the disciples and they spoke in other languages, and the crowd heard God’s works in their own native tongues (Acts 2:1-13). In Corinth, the gift appears again, but Paul has to correct how it was being used in church meetings. His summary is simple: tongues are a real gift of the Spirit, they are directed to God, they build up the speaker, and in a public gathering they need interpretation so the whole church is built up (1 Corinthians 14:2-5). Paul never forbids the gift. He does insist that love and order come first.

What exactly is the gift of tongues in the Bible?

The Greek word behind “tongues” means languages or tongues. In Acts 2, the content is clearly human languages:

And when this sound rang out, a crowd came together in bewilderment, because each one heard them speaking his own language. — Acts 2:6 (BSB)

The visitors from many nations were bewildered because they heard the wonders of God in the tongue they were born into.

In 1 Corinthians 14, Paul describes something a little different. He says, “For he who speaks in a tongue does not speak to men, but to God. Indeed, no one understands him; he utters mysteries in the Spirit” (1 Corinthians 14:2). That sounds like speech that the hearers do not recognize, which is why Paul later says it must be interpreted in the church.

So the Bible uses one word for a gift that shows up in at least two settings: a public sign to unbelievers who hear their own language, and a personal prayer language directed to God. Both are called tongues, and both are traced to the Holy Spirit.

The gift appears in a few other places. On the Gentiles at Cornelius’s house, the Spirit fell and they were speaking in tongues and exalting God (Acts 10:46). At Ephesus, when Paul laid hands on some disciples, they spoke in tongues and prophesied (Acts 19:6). Paul also lists tongues among the Spirit’s gifts in 1 Corinthians 12:10 and 12:28-30, where he asks pointedly whether all speak in tongues — a question that expects the answer no, since the Spirit distributes gifts as He wills.

Why does Paul say tongues are a sign for unbelievers?

Paul quotes Isaiah to make his point: “By strange tongues and foreign lips I will speak to this people, but even then they will not listen to Me, says the Lord” (1 Corinthians 14:21). Then he draws the conclusion: “Tongues, then, are a sign, not for believers, but for unbelievers. Prophecy, however, is for believers, not for unbelievers” (1 Corinthians 14:22).

The background is judgment. In Isaiah’s day, God spoke to a stubborn people through the foreign speech of an invading army. Tongues carry that same sign value: God is speaking, and the hearer must respond. At Pentecost, the sign worked exactly that way — outsiders heard God’s works in their own languages and asked what it meant.

But Paul immediately adds a warning. If the whole church speaks in tongues at once and an outsider walks in, “will they not say that you are out of your minds?” (1 Corinthians 14:23). The sign can turn into confusion if it is used without care. Prophecy, by contrast, speaks plainly to people, so that “the secrets of his heart will be made known” and the visitor falls down and worships God (1 Corinthians 14:24-25).

Can tongues be used in a church service, and under what rules?

Yes, but Paul gives clear limits. In 1 Corinthians 14:26-27 he writes:

What then shall we say, brothers? When you come together, everyone has a psalm or a teaching, a revelation, a tongue, or an interpretation. All of these must be done to build up the church. If anyone speaks in a tongue, two, or at most three, should speak in turn, and someone must interpret. — 1 Corinthians 14:26-27 (BSB)

If no interpreter is present, Paul says the speaker should remain silent in the church and speak to himself and to God (1 Corinthians 14:28). He closes the chapter with two short commands: do not forbid speaking in tongues, and let everything be done in a proper and orderly way (1 Corinthians 14:39-40).

So the Bible’s rule is not “never” and not “always.” It is: tongues are welcome, but they must serve the church, and they must be interpreted so that everyone can say Amen.

What does it mean to pray in the Spirit or pray in tongues?

Paul writes, “I will pray with my spirit, but I will also pray with my mind. I will sing with my spirit, but I will also sing with my mind” (1 Corinthians 14:15). He is describing prayer that comes from the spirit rather than the understanding — which is why he can also say, “I thank God that I speak in tongues more than all of you” (1 Corinthians 14:18), while adding that in church he would rather speak five understandable words than ten thousand in a tongue (1 Corinthians 14:19).

Many Christians connect this with Romans 8:26, where Paul says the Spirit helps us in our weakness and intercedes for us with groans too deep for words. Others read that verse as referring to the Spirit’s own intercession rather than to a believer’s prayer language. Either way, the point of praying in the Spirit is communion with God, not performance for an audience.

Paul also commands believers to be filled with the Spirit and to speak to one another in psalms, hymns, and spiritual songs (Ephesians 5:18-19). Whatever your view of tongues, prayer and worship that come from the heart are commanded for every Christian.

Do all Christians have to speak in tongues?

This is where faithful Christians differ, and the difference is worth stating honestly.

Some Christians, often called Pentecostal or charismatic, hold that tongues is a gift available today and that it is often the initial evidence of the Spirit’s filling, based on the pattern in Acts. They point to Acts 2, Acts 10:46, and Acts 19:6, where tongues accompany the Spirit’s coming. Many of them also practice a private prayer language for personal devotion.

Other Christians, often in the historic Protestant and Reformed traditions, hold that tongues was a genuine gift in the apostolic era but that it has ceased, or at least is not normative for the church today. They point to 1 Corinthians 12:30, where Paul’s question implies not everyone speaks in tongues, and to the fact that tongues served as a sign at the birth of the church.

A third group, including many evangelicals, holds that the gift may still be given today but is not required of any believer. They would say: do not forbid it, do not demand it, and test everything by Scripture.

What all these groups agree on is that the Holy Spirit is given to every believer, that no one is a second-class Christian for lacking a particular gift, and that love is the greatest thing (1 Corinthians 13). Paul’s own words set the tone: “I wish that all of you could speak in tongues, but I would rather have you prophesy” (1 Corinthians 14:5). He wanted the church built up, not divided over gifts.

How should I think about tongues in my own life?

Start with Scripture. Read Acts 2 and 1 Corinthians 12–14 slowly, in order, and ask what Paul actually commands and what he leaves open. Notice that he never tells anyone to seek tongues as the mark of salvation. He tells everyone to pursue love and to desire spiritual gifts, especially prophecy, so that others are built up (1 Corinthians 14:1).

Then pray. Ask God for whatever gifts He chooses to give, and ask Him for wisdom about how to use them. If you are unsure about a practice in your church, talk with your pastor or a mature believer who knows you. If you are drawn to pray in a way you do not understand, do it privately before God, and keep your public worship orderly and understandable.

Finally, stay rooted in a local church. Gifts were never meant to be solo possessions. They are given for the common good (1 Corinthians 12:7), and the body of Christ is where they are tested, used, and grown. Whatever your experience with tongues, the goal is the same: to love God, love His people, and speak and pray in a way that points to Jesus Christ.

Common questions

Is speaking in tongues still for today?

Christians disagree. Pentecostal and charismatic believers say yes, and point to Acts and 1 Corinthians as ongoing gifts. Many Reformed and cessationist Christians say the gift served the apostolic era and is not normative now. Other evangelicals hold that it may still be given but is not required. All agree the Spirit is given to every believer.

Do I have to speak in tongues to be saved?

No. The Bible never makes tongues a condition of salvation. Salvation is by grace through faith in Jesus Christ alone. Paul’s question in 1 Corinthians 12:30 implies not all speak in tongues, and he calls love the greatest gift in 1 Corinthians 13.

What is the difference between speaking in tongues and praying in the Spirit?

Paul describes both praying with his spirit and praying with his mind in 1 Corinthians 14:15, and he speaks of tongues as speech directed to God (1 Corinthians 14:2). Many Christians use “praying in the Spirit” for prayer that comes from the spirit rather than the understanding, while others connect that phrase to the Spirit’s own intercession in Romans 8:26.

Can tongues be used in a church service?

Yes, with order. Paul allows two or at most three to speak in turn, and only if someone interprets so the church is built up (1 Corinthians 14:27-28). He also says not to forbid speaking in tongues, and that everything must be done in a proper and orderly way (1 Corinthians 14:39-40).
