Cornelius said:
1Co 13:8 Love never faileth: but whether there be prophecies, they shall be done away; whether there be tongues, they shall cease; whether there be knowledge, it shall be done away.
1Co 13:9 For we know in part, and we prophesy in part;
1Co 13:10 but when that which is perfect is come, that which is in part shall be done away.
1Co 13:11 When I was a child, I spake as a child, I felt as a child, I thought as a child: now that I am become a man, I have put away childish things.
I know it says that it shall be "done away with" but we have to be fair when we read this and admit that Paul says this will happen when....................1Co 13:10 .... when that which is perfect is come,
One the things not easily seem in the english text is the voice of the verbs. The voice for prophecies and knowledge in verse 8 is passive. The voice for the verb that relates to tongues is middle.
This pattern follows in verse 9. Notice tongues is not mentioned in verse 9. In verse 9 Paul says we know in part, and we prophesy in part, but he omits mentioning speaking in tongues. I suggest the reason he omits the mention of tongues is because of the voice of the verbs in verse 8. The "perfect" is the acting force that causes Prophesy and Knowledge to pass away.
In essence, I dont think one can exegetically establish a relationship between tongues and the coming of the perfect.
So far I have offered no answers as to why the verb "cease" in verse 8 is in the middle voice. Of course the middle voice is difficult to relate in english. It speaks of the action being preformed by the subject upon itself. So then, tongues will cease of themselves. This also fits with the perfect not being related to tongues ceasing.
This raises the question when do tongues cease, and why did they cease.
I believe it was Vic C who said....
What is a sign and who were signs for, then and now? < That would be a good side-study.
To this I reply B I N G O.
Vic C is certainly asking the right questions. When will the sign of tongues cease of itself? Could it be when it gives the sign to the event it signifies? What event did NT tongues signify? To answer this one must ask what purpose the sign of tongues fulfilled. 1 Cor 14 says...
21 In the law it is written, By men of strange tongues and by the lips of strangers will I speak unto this people; and not even thus will they hear me, saith the Lord.
22 Wherefore tongues are for a sign, not to them that believe, but to the unbelieving: but prophesying is for a sign, not to the unbelieving, but to them that believe.
Of course the event quoted by Paul is not the beginning. One must go all the way back to Deuteronomy to understand why the Assyrians were speaking to the Jews an Aramean. In the curses of Deuteronomy, foreign tongues were a sign of Jewish disobedience. So then, in Acts, God was giving the Jewish unbeliever a sign that the Jewish nation was being partially and temporarily rejected on the basis of the curses in Deuteronomy.
Then comes the tongues events in the diaspora. The Jews were again presented with this sign of their disobedience.
If I can conclude with a small item of speculation. This whole biblical phenomenon makes me wonder what they saints of Acts two were saying to the unbelieving Jewish crowd when they spoke in the languages of the world. I know there is no way for me to know, but I suspect that they were calling the unbelievers to repentance.
