The operation of the Church is the operation of the Church, so why would it be different back then compared to now.
If they spoke in tongues back then it would apply today, and it was more than the disciples, and Paul speaking in tongues, so if the people that were not disciples, or Paul, spoke in tongues they would be able to speak in tongues today.
1Co 14:39 Wherefore, brethren, covet to prophesy, and forbid not to speak with tongues.
1Co 13:13 And now abideth faith, hope, charity, these three; but the greatest of these is charity.
Out of faith, hope, and charity, love in action, charity is the greatest, and faith and hope are not needed in heaven, but love will go on forever.
1Co 13:8 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.
1Co 13:9 For we know in part, and we prophesy in part.
1Co 13:10 But when that which is perfect is come, then that which is in part shall be done away.
Love never fails.
I do not believe this means tongues have ceased but when the saints are in heaven that perfect is come, and in heaven all these things prophesies, tongues, knowledge of what we learned on earth will not be needed in heaven like faith and hope are not needed, but love will go on forever, for love never fails.
All that we did on earth concerning living for God will not be needed in heaven, but love will go on forever.
I believe that is what it is saying not that tongues have ceased at any point while we are on earth.
And God said He will create a new heaven and earth, and the former shall not be remembered, nor come to mind, so when the saints are at the New Jerusalem they will not remember anything prior to it, and will not remember the earth, and what happened on it, for the prior creation is associated with sin and rebellion, and God does not want them to know about that, and they will not feel sad for their loved ones, and people they cared about that were not saved.
