The passage says: Love never ends. As for prophecies, they will pass away; as for tongues, they will cease; as for knowledge, it will pass away. For we know in part and we prophesy in part, but when the perfect comes, the partial will pass away.  When I was a child, I spoke like a child, I thought like a child, I reasoned like a child. When I became a man, I gave up childish ways.  For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.

 First, the “perfect” is described as a person, not a thing.  When the “perfect” comes, you will see the “perfect” face to face, and you will be fully known by the “perfect.”  The “perfect” can only be Jesus who is coming.

Second, when the “perfect” comes, not only will tongues cease but so will knowledge and prophesy.  Are those who argue that the speaking in tongues ceased saying that the church has no more knowledge?

Third, Jesus anticipated that as long as there would be the proclaiming of the gospel, there would be believers, and as long as there would be believers, speaking in tongues would accompany them: And he said to them, “Go into all the world and proclaim the gospel to the whole creation.  Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.  And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues…[1]  If the proclaiming of the gospel will not cease until the coming of Jesus, neither will the speaking in tongues.
