If you want to understand the function of tongues, you must understand the function of parables. How are the two related? Listen carefully:
Then the disciples came and said to him, "Why do you speak to them in parables?" And he answered them, "To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away. This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. Indeed, in their case the prophecy of Isaiah is fulfilled that says: "'You will indeed hear but never understand, and you will indeed see but never perceive. For this people's heart has grown dull, and with their ears they can barely hear, and their eyes they have closed, lest they should see with their eyes and hear with their ears and understand with their heart and turn, and I would heal them.' (Matthew 13:10-15)
The secrets of the kingdom of heaven have been given to God’s elect. And to those who have faith, more will be given. But to those whose hearts are hardened against the Lord, who are destined for destruction, they will be ever hearing, but never able to understand. Parables are interpreted or divinely revealed to the children of the kingdom of heaven. Sounds familiar? Does Paul not command the Corinthians to be quiet unless there is an interpretation or a divine revelation? Why does Paul say that tongues should be practised as such in the church? Consider the fact that Paul emphasizes the greatest of gifts, which is love, in 1Corinthians 13. Consider the fact that Paul compares tongues and prophecy in 1Corinthians 14. What is the relationship between the three? We must ask ourselves the following question: “Am I using the gift of tongues to edify the body of Christ in love, or am I using the gift of tongues in a selfish way and trying to bypass God’s provisions in Christ to acquire special powers?” Uninterpreted tongues do not serve the body of Christ; but, interpreted tongues become a word of prophecy, knowledge, revelation, or teaching (1Corinthians 14:6).
Tongues without understanding is a sign of judgment unto those whose hearts are calloused and hardened. Tongues with understanding (prophecy) is a sign of blessing from God, sometimes piercing the heart with conviction of sin to bring to salvation, other times bringing encouraging revelation from God to the assembly of believers. That is why it is written: “By people of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord." Thus tongues are a sign not for believers but for unbelievers, while prophecy is a sign not for unbelievers but for believers (1 Corinthians 14:21-22).
Consider the fact that both the meaning of parables and the meaning of tongues comes from God’s dealings with rebellious Israel through Isaiah, and the ensuing judgment that would come through the Assyrian king (Isaiah 6:8-13; Isaiah 28:11-22). Now, it makes sense why the disciples would speak in the tongues of the Gentiles in the book of Acts, because judgment came upon calloused Israel, which has been broken off so that the Gentiles might be grafted into the olive root (Romans 11:11-32).
Tongues, then, should be practised in this context. Understanding this concept, and understanding the greatest gift of love, we should seek the edification of the body of Christ, rather than seeking special powers through an ecstatic experience. There is much misunderstanding of tongues in the church, and the evil one is taking advantage of this. At the very least, we must test the spirits (1John 4:1; 1Thessalonians 5:21-22). How can we test the spirits unless we understand what is being spoken? Do the tongues or does the message bring attention to the work of Christ, or does it bring attention to the person babbling, the powers that are sought, the ecstatic experience, or any other thing for that matter?
The Holy Spirit testifies to Jesus Christ, His person, His work, His salvation. A spirit that does not bring attention to Christ cannot be of God. With that being said, let us not forbid the speaking of tongues, but let us do it appropriately, in accordance with the revealed will of God.
Yours in Christ,
