1 Cor 14:21 on God's use of tongues?
What does 1 Corinthians 14:21 reveal about God's communication through foreign languages and tongues?

Text of 1 Corinthians 14:21

“In the Law it is written: ‘By strange tongues and foreign lips I will speak to this people, but even then they will not listen to Me,’ says the Lord.”


Immediate Context in 1 Corinthians 12–14

Paul is correcting misuse of spiritual gifts in Corinth. Chapters 12–14 form a single argument: gifts are from one Spirit, love must govern their use, and intelligibility is essential for congregational edification. Verse 21 stands at the heart of chapter 14’s contrast between unintelligible tongues and prophecy that builds up the church.


Old Testament Citation: Isaiah 28:11–12

Paul quotes Isaiah’s oracle against Ephraim and Jerusalem. God warned His covenant people that, since they refused clear prophetic speech, He would address them through “stammering lips and a foreign tongue” (Isaiah 28:11) — the Assyrian invaders. Foreign speech, therefore, functioned as a sign of judgment on hardened hearers. Paul reapplies that principle to first-century unbelief: ecstatic or foreign languages are meaningful to God, but to the unbelieving ear they underscore spiritual distance.


God’s Sovereign Freedom in Choosing Mediums

The verse reveals that the Creator is not bound to one linguistic conduit. He may employ languages previously unknown to the speaker (Acts 2:4) or to the hearer (Isaiah 28:11). This highlights divine initiative: communication belongs to God; comprehension is a grace.


Tongues as a Sign — Both Judicial and Missional

1. Judicial Sign: For Israelites who rejected plain revelation, unfamiliar speech exposed their hardness. So in Corinth, uninterpreted tongues leave unbelievers thinking the assembly is mad (14:23). The phenomenon itself testifies against refusal to listen.

2. Missional Sign: At Pentecost, the same gift drew thousands because visitors heard “the wonders of God” in their native languages (Acts 2:8–11). When interpreted, tongues can catalyze faith.


Connection to Babel and Pentecost

• Babel (Genesis 11): God’s judgment scattered languages, impeding human arrogance.

• Pentecost (Acts 2): God’s redemptive act unified diverse languages under the gospel. 1 Corinthians 14:21 stands between these poles, showing that language can either humble pride or herald salvation, depending on receptivity.


Theological Implications

• Universality: God desires to be known among every tribe and tongue (Revelation 7:9).

• Human Responsibility: Rejection persists even when God stoops to unfamiliar idioms (14:21b).

• Christocentric Fulfillment: The resurrected Christ pours out the Spirit (Acts 2:33), empowering multilingual witness as foretold.


Practical Guidance for Congregations

• Tongues without interpretation edify the speaker (14:4) but not the body; prophecy is preferable in public worship (14:5, 19).

• Two or three tongues, each in turn, with interpretation (14:27–28) honors both the Spirit’s freedom and the mind’s need for sense.

• Foreign-language ministry today—whether supernatural or through studied linguistics—must aim at clear gospel proclamation.


Psychological and Behavioral Observations

Research on native-language cognition confirms deeper emotional resonance when people hear vital truths in their heart language. Scripture anticipated this by emphasizing intelligibility (14:9). God’s design meets human cognitive structure.


Archaeological and Historical Corroboration

Inscriptions from the Jewish catacombs in Rome (1st–3rd centuries AD) appear in Greek, Latin, and Hebrew, illustrating early Christian multilingual reality. Church Fathers (e.g., Irenaeus, Against Heresies 5.6.1) record missionary tongues, aligning with Paul’s teaching.


Eschatological Foretaste

Multilingual praise in the Spirit anticipates the final assembly where redeemed nations worship the Lamb (Revelation 5:9). Tongues thus serve as a down payment of the coming kingdom.


Answer to the Question

1 Corinthians 14:21 discloses that God, in sovereign grace and judgment, employs foreign languages to communicate with humanity. When hearts are hardened, unfamiliar tongues expose unbelief; when hearts are receptive, the same gift becomes a bridge to salvation. The verse affirms God’s freedom, mankind’s responsibility, and the necessity of intelligible proclamation so that all may glorify Him.
