Short answer: In Mark 16:17, Jesus says that speaking in new languages will be a sign accompanying those who believe in him. This promise is tied to the mission of preaching the gospel globally, not as a requirement for salvation but as a confirming mark of believers. The text presents tongues as a divine enablement, not a universal experience. It is part of Jesus’ broader vision for the spread of the gospel.
Jesus promises signs to confirm the Gospel's spread
Mark 16:17 comes as part of Jesus' final instructions after rising from the dead. He has just commanded his followers to take the good news everywhere, making belief and baptism central to salvation (Mark 16:15–16). Now he describes supernatural confirmations that will accompany their preaching. The list, casting out demons, speaking new languages, handling snakes, surviving poison, and healing the sick, serves as validation for their mission. These signs are not random displays of power but proofs tied directly to their work as messengers. Jesus presents them as divine authentication for the unprecedented claim that salvation has come through a crucified Messiah.
The specific signs connect to real challenges the first believers faced. Speaking in tongues served as a miraculous bridge for cross-cultural gospel work (Acts 2:4–11), while immunity to snakebite mirrored Paul's experience in Malta (Acts 28:3–6). Healing authenticated their message in a culture expecting prophets to perform wonders. Jesus frames these phenomena as organic outcomes of faithful proclamation, not as techniques believers should seek or test. The passive construction (“these signs will accompany”) keeps God as the one initiating the miracles, not humans demanding them. The signs exist for the gospel’s sake, not the preacher’s reputation.
This passage belongs to the unique apostolic era when God confirmed the new covenant message with extraordinary acts. The book of Acts shows these signs appearing exactly as described, when the gospel first entered a region or when Jewish hearers needed validation (Hebrews 2:3–4). Jesus never instructs believers to chase these manifestations as personal spirituality badges. Instead, the signs follow those already engaged in Christ’s global mission. Their primary purpose was temporary: to establish the truth of the resurrection until the New Testament scriptures were complete. The enduring call remains verse 15’s commission to preach, not verse 17’s miraculous confirmations.
The meaning of speaking with new languages
In Mark 16:17, Jesus mentions that believers will speak with “new languages.” This phrase points to supernatural verbal expressions enabled by the Holy Spirit, not ordinary human languages learned through study or practice. The word “new” emphasizes that these are fresh, Spirit-given utterances, distinct from known dialects or tongues. This aligns with the broader biblical theme of the Holy Spirit empowering believers for God’s purposes, as seen in Acts 2:4–11. The focus here is not on human effort but on divine enablement, highlighting God’s action in equipping His people for ministry.
The context of this verse is crucial. Jesus lists several signs that will accompany believers, including casting out demons, healing the sick, and speaking with new languages. These signs are not prerequisites for faith but evidences of God’s power working through those who believe. The phrase “these signs will accompany those who believe” shows that these miracles flow from genuine faith rather than being produced by it. This distinction helps us avoid misunderstanding the purpose of these signs, which is to authenticate the gospel and demonstrate God’s kingdom breaking into the world.
It’s important to approach this verse with care. While speaking with new languages is listed as a sign, it is not presented as a universal experience for all believers or a measure of spiritual maturity. The emphasis is on God’s power, not human performance. This prevents us from pressuring others to seek tongues or treating it as a litmus test for faith. Instead, we can celebrate the diverse ways God works through His people, trusting that He equips each believer uniquely for His purposes.
Speaking in tongues as a sign of belief, not a test of faith
Jesus links speaking in new languages directly to belief, not to personal spiritual achievement. In Mark 16:17, he includes tongues among several signs that “will accompany those who believe,” placing it alongside exorcisms and healings as evidence of God's power at work. This follows his global mission command (Mark 16:15), suggesting these signs validated the gospel's spread, especially where hearers needed confirmation beyond words. The text makes no distinction between “ordinary” and “spirit-filled” believers, the promise is for all who trust Christ, though not all may experience every sign in the same way.
The context shows these signs served a specific purpose in the early church's witness. The snake-handling and poison-drinking references (Mark 16:18) connect to apostolic experiences like Paul's viper bite in Acts 28:3–6, not to ongoing practices for all believers. Similarly, tongues functioned as a temporary authenticating sign, particularly for Jewish audiences (1 Corinthians 14:21–22). Jesus presents these phenomena as God-initiated accompaniments to faith, not human-generated proofs we must replicate. The focus stays on the gospel's advance, not on individual supernatural experiences as markers of spiritual superiority.
This passage discourages both pressure and presumption regarding tongues. Jesus never commands believers to seek specific signs, nor does he promise all will speak in tongues. The text guards against recklessness (no mandate to handle snakes) and against judging others' faith by particular gifts. What remains central is the mission: these signs follow “those who believe” as they proclaim Christ. Where tongues or healings occur today, they point to God's power, not human ability. Where they don't, salvation is equally secure for “he who believes and is baptized” (Mark 16:16). The signs serve the Savior, not the other way around.
Tongues as a sign tied to Christ's mission
Mark 16:17 places speaking in new languages among several signs that “will accompany those who believe.” The setting is Jesus' final commission to take the gospel worldwide (16:15), suggesting these signs validated the message as it crossed cultural barriers. Unlike the other signs listed, exorcisms, healing, and supernatural protection, tongues specifically addressed the language divide. The text makes no distinction between apostles and other believers, nor does it specify if these signs would continue past the apostolic era. What remains clear is their purpose: confirming Christ's authority as the gospel advanced into new territory.
Disagreement arises over whether tongues continue today. Some argue the signs in Mark 16:17–18 were temporary authenticating marks for the early church's foundational mission, noting similar signs cluster around key advances in Acts. Others see an ongoing pattern whenever the gospel enters unreached cultures, citing modern missionary accounts. Both views agree the text itself sets no expiration date but connects tongues to global witness, not personal spirituality. The real divide is whether we should expect identical manifestations today or recognize that signs may take different forms while serving the same validating purpose for the unchanging message.
Two boundaries keep this passage from misuse. First, tongues are never commanded here, they “will accompany” belief, not define it. Pressuring believers to seek tongues misreads the text, which emphasizes Christ's authority, not human performance. Second, the signs serve the gospel's advance, not personal thrill or testing God's protection (unlike the snake-handling some extract from 16:18). When Acts records tongues, it's always amid cross-cultural gospel proclamation. However we interpret their continuation, Mark 16:17 anchors tongues to the mission Jesus gave, not individual ecstatic experience. The signs point beyond themselves to the Savior who commissioned them.
Signs confirm the risen Christ's authority
Jesus links these miraculous signs, including speaking in new languages, directly to believers, not as universal guarantees but as confirmations of his authority. The risen Lord, now seated at God's right hand (16:19), deploys these manifestations to display his ongoing reign. Just as tongues at Pentecost reversed Babel's curse (Acts 2), these signs declare Christ's victory over chaos. Yet they remain his gifts to distribute, not achievements to demand. The text emphasizes “those who believe” (16:17), the signs follow faith in Christ, not the other way around. Our focus stays on the Giver, not the gifts.
The specific mention of “new languages” (16:17) signals the gospel's global reach, fulfilling the commission to preach to “the whole creation” (16:15). Unlike pagan ecstatic speech, these tongues serve communication, as at Pentecost when pilgrims heard the wonders of God in their dialects (Acts 2:11). The gift dismantles barriers, proving Christ's power to unite what sin divided. But Mark mentions this sign alongside others, demonstrating that no single gift defines faith. The risen Christ chooses varied ways to authenticate his message, always pointing people back to salvation through belief (16:16).
These signs accompany the gospel's advance, not replace it. Snake-handling and poison-drinking (16:18), while literal for some early believers, primarily symbolize Christ's protection amid Kingdom warfare. Similarly, tongues display the Spirit's presence without becoming the measure of spiritual maturity. The text's center remains Christ's command (16:15) and promise (16:16), not the signs themselves. When gifts like tongues appear, they serve one purpose: confirming that the crucified Jesus is now the reigning Lord. Every spiritual gift, including tongues, exists to make much of him, not the experiences of his people.
How to approach spiritual gifts with faith and wisdom
Mark 16:17 mentions speaking in new languages as one of several signs that may accompany believers. This verse reminds us that spiritual gifts, including tongues, are given by Jesus for his purposes, not as trophies for personal spirituality. The focus here is not on the gifts themselves but on the authority of Christ’s name and the mission to proclaim him. Churches should avoid elevating any single gift as proof of faith or salvation. Instead, we are called to prioritize the gospel message, trusting that the Holy Spirit equips believers in diverse ways for the work of the kingdom.
At the same time, Mark 16:17 does not suggest that every believer must speak in tongues or that tongues are essential for salvation. The verse is descriptive, not prescriptive, it describes what can happen, not what must happen. This frees us from pressure to seek specific gifts or judge others based on their experiences. Faithful response means remaining open to the Spirit’s work while grounding everything in Scripture. Churches should test all manifestations of spiritual gifts against biblical truth, ensuring that Christ remains central and that no gift is misused or misunderstood.
Practical wisdom also matters when applying Mark 16:17. While the verse mentions signs like speaking in tongues and healing, it does not encourage reckless behavior or testing God’s protection, such as handling venomous snakes. Instead, it points to the Spirit’s power working through believers for the sake of the gospel. In ordinary life, this means using spiritual gifts to serve others and glorify Christ, not to draw attention to ourselves. Whether or not we experience tongues, our primary calling is to share the good news of Jesus, trusting that God will work in and through us as he sees fit.
Biblical fidelity check
This passage requires care because it appears in a disputed ending of Mark's Gospel (16:9–20), absent from some early manuscripts. While still Scripture, we read it with awareness that its promises about signs like tongues come alongside Jesus' ascension (16:19), suggesting their role in launching the church's mission. The text doesn't specify whether “speak with new languages” (16:17) refers to known human tongues or ecstatic utterances, nor does it state if this gift continues today. What remains clear is that these signs validated the gospel's power during the apostolic era, not the believer's spiritual superiority.
The key disagreement lies in whether tongues continue as a normative experience for all believers or were temporary signs authenticating the apostles' message. Continuationists see 16:17 as affirming ongoing spiritual gifts, while cessationists connect it to the unique authority of the first-century church. Both views agree the text presents tongues as a divine sign, not a human achievement, and that Christ's command to preach globally (16:15) remains central. The passage ultimately points not to the phenomena themselves but to Jesus' authority over all creation, including the supernatural (16:19).
