This shows that the gift of tongues is intended as a sign not to those who believe but to unbelievers, but prophecy is intended not for unbelievers but for those who believe.
Let's look at the first recorded use of "tongues" in the Book of Acts:
Acts 2:1-11
2:1 And when the day of Pentecost had come, they were all together in one place. 2 And suddenly there came from heaven a noise like a violent, rushing wind, and it filled the whole house where they were sitting. 3 And there appeared to them tongues as of fire distributing themselves, and they rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance.
5 Now there were Jews living in Jerusalem, devout men, from every nation under heaven. 6 And when this sound occurred, the multitude came together, and were bewildered, because they were each one hearing them speak in his own language. 7 And they were amazed and marveled, saying, "Why, are not all these who are speaking Galileans? 8 "And how is it that we each hear them in our own language to which we were born? 9 "Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and visitors from Rome, both Jews and proselytes, 11 Cretans and Arabs — we hear them in our own tongues speaking of the mighty deeds of God. "
NASB
The Greek word for "tongues" used here in Acts 2:3 is diamerizómenai gloóssai. In English it means "distributed languages". This is the key. There were 16 languages being spoken and HEARD and that was the miracle. This was an historical event that was taking place. The disciples were preaching and over 16 languages were being heard AT THE SAME TIME. The greek word "gloóssai" means language, and a language that can be understood by those hearing it.
For centuries this debate on tongues has taken place. Paul addresses it in I Corinthians 14, as it was an issue even in the early Church. We can only interpret this Greek word one way, "language". The gift of "tongues' is actually the gift of "languages". Who needs this gift today? Any missionary on the mission field who cannot speak the language of the people God has called them to minister to. But has anyone ever heard of this actually happening on the mission field as it did on the Day of Pentecost? No, because we have been practicing humanistic Christianity and only seek that which makes us happy, that which makes us feel important, that which makes us FEEL good inside.

Each time we see the word "tongues" used in the New Testament, 26 times, it is the same Greek word. This word cannot mean one thing in one verse and something else in another. Only one time in the New Testament is there a different word used that is interpreted as "tongues" in English: I Corinthians 14:21 where Paul quotes Isaiah 28:11 and the Hebrew word is translated into the Greek "heterogloóssois" which literally means "othertongued, i.e. a foreigner. In Acts 2:6 the Greek word "dialektos" is used which literally means "dialect" or a "mode of discourse". Again, another reference to an actual spoken language. The focus here is not on the "tongues", but rather the fact that the Gospel was heard by many in their own language and over 2,000 people were saved that day through the power of the Holy Spirit.
In the Law it is written, "By men of strange "languages" and by the lips of strangers I will speak to this people, and even so they will not listen to Me," says the Lord.
So, after having studied this topic and I Corinthians 14 for some 30 plus years, I can draw no other conclusion than this:
The gift of "languages" is still needed today, it is still given today by the Holy Spirit when He wills, for the furtherance of His Gospel and this other "gift" that is talked about so much, that creates so much "chaos" in the Church today, is nothing more than Satan's attempt to tear the Church apart, to get the Church to disagree on yet another important "point" of doctrine. Doctrine that was created by "man" and not God.
But, how does one know if one is "filled with the Holy Spirit"? But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. Now those who belong to Christ Jesus have crucified the flesh with its passions and desires. If we live by the Spirit, let us also walk by the Spirit. Let us not become boastful, challenging one another, envying one another. Gal 5:22-26 NASB
If you are filled with the Holy Spirit, you will exhibit the fruit in your walk. If you are not filled with the Spirit, there will be no fruit. I don't see "tongues" listed above. God wants us to be filled with His fruit and He will give us the "gifts" that He wants us to have when He wants us to have them and when we will need them to make disciples of all "nations".
