I Corinthians 14:10 "There are, it may be, so many kinds of voices in the world, and none of them is without signification."Lets take a look at the word "signification", and in the text it is # 880 in the Greek dictionary. "aphanos, af-o-nos; voiceless, mute, by choice without meaning; dumb." So lets now see what this verse is really saying. "There are, it may be, so many kinds of voices in the world, and none of them is dumb and without meaning." Every language in the world makes common sense to the user of that tongue. Each word in the languages of the world is a sign of something that gives meaning to the one using that word. If every word means something and has a value, then don't blow hot air. I Corinthians 14:11 "Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me."Paul is saying, if I can't speak another man's language, I am looked on as a barbarian to that man. And if that man speaks to me in his native tongue and I don't understand him, then that person is a barbarian to me. "Barbarian" in the Greek as used here is a "foreigner". You can't understand him and he cannot understand you, you might as well be speaking to the wall. Are you starting to get the picture? If you are going to teach the Scripture, then either know the language, or get a interpreter that understands completely what you are trying to say. I Corinthians 14:12 "Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church."Paul is saying that it is nice that you want to get the Word of God out to these foreigners, however see to it that everything that you say is in the language that will edify and build up the body of Christ that you are speaking to. Without an interpreter anything you say is nothing but ignorance. You simply can't go to a Spanish speaking church and teach in English or it become nothing but Babel. We are not talking about what many call tongues, for that is not what happened on Pentecost day. For on Pentecost day everyone heard and understood clearly every word in their native tongue all at the same time. That is what is called the "cloven tongue", and that was the evidence of the presence of the Holy Spirit. I Corinthians 14:13 "Wherefore let him that speaketh in an unknown tongue pray that he may interpret."Let him that speaks in an unnatural language pray that what he says will be interpreted properly. Before you go to speak to foreigners, pray that God will give you the understanding of that language before you go. If you go without this preparation, you are wasting your time. I Corinthians 14:14 "For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful."If you pray in a language that your mind doesn't understand, then of what benefit is your prayer. You uttered words that mean nothing, and have created nothing but noise. When you pray to the Father, know exactly who you are praying to and for what purpose. However if you are just muttering words and sounds that have no meaning, your prayer is in vain. In short, you have to be able to communicate, before people know what you are saying. Remember that this chapter is dealing with teaching those that are foreigners to you, and those that do not speak your language. The ability to communicate is a gift from God. I Corinthians 14:15 "What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also."When you pray you must be in tune with the Holy Spirit, and your mind must have the understanding of what you are doing. Paul is saying that when he prays in the Spirit, or sings songs to the Lord, he will do it in the tongue or language that gives him understanding of what he is praying and singing. This is just common sense, for you use the language that you know and are accustomed with, when you pray, sing, teach or talk to others. In this way you will be fruitful in what you are doing. I Corinthians 14:16 "Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say "Amen" at thy giving of thanks, seeing he understandeth not what thou sayeth?"When you are speaking in English and the rest of the non-English speaking people have no idea of your thoughts, they simply will not know when it is time to say "Amen". It is hard to understand why anyone cannot understand this chapter and what Paul is saying, with just a little effort. Paul is telling us that if we cannot communicate with another person to were they can understand what we have to say, then just don't say anything. I Corinthians 14:17 "For thou verily givest thanks well, but the other is not edified."If you are praying and give thanks in the presence of foreigners, then they have not gained on thing from your prayer. In fact they have no idea of what your even talking about. I Corinthians 14:18 "I thank my God, I speak with tongues more than ye all:"Again Paul is referring to the many languages that he spoke. Paul was a Roman, and spoke Latin, and as a Jew he was trained in the Hebrew, Chaldee and the Greek. His father came from Tarsus which is in Turkey of today, and that gave him another tongue, so we see that Paul was fluid in many languages through his home and training.
