Thanks for your careful answer
I learned personally to never base a whole dogma or teaching based on one verse. But even so, when the tongues will cease, what about knowledge... look:
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. 1 Cor 13:8
I do not think knowledge is gone...vanished. I think it will all cease, vanish when Jesus Christ returns and/or we enter heaven.
Lets even take the context, in Pauls time his letters had no chapters:
Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
9 For we know in part, and we prophesy in part. 10 But when that which is perfect is come, then that which is in part shall be done away.
11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.
(Chapter14) 1 Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. 2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries.
3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort. 4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
I do not think Paul would first write "it all ceases after a while" and
than write: "desire spiritual gifts". That does not make sense to me.
Groaning well I can understand that might be a thought. But in my case: I hear myself speak words, some words return, and than I would say these words make sentences. I do not speak "sounds" like you may see on this charismatic tv programs sometimes. It are words. I cannot learn this language myself. But sometimes I find out I speak new words that sound perfectly fine between the sentences I know. I hope this make sense to you
