I would agree with notuptome. My two cents...
First they served as a purpose to full the prophecy of Isaiah 28. Signs as that seen, that cause us to wonder, the faith principle. They are designed for the those who rebel showing they did not believe the word of God prophecy. Prophecy is designed for those who did believe God according to His prophecy.. 1Co 14:22
That is not the point Paul draws out of Isaiah 28:11.
Isa 28:11 For with stammering lips and another tongue will he speak to this people.
1Co 14:22 Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe
Paul goes on to give an example of all in a church speaking in tongues and unbelievers saying 'ye are mad.' That's a sign. When unbelievers hear tongues, 'and yet for all that, they will not hear Me.' That prophecy is fulfilled when unbelievers hear speaking in tongues-- and that fulfilled prophecy is a sign.
In this day and age, there are still plenty of people who do not believe. There are even Jews who do not believe. Isaiah 28 is not an argument for tongues ceasing.
It is one of the manners he brought new revelations when we had them in part. The perfect or complete has come with the last chapter called Revelation.
When the perfect comes, the Paul's understanding will be so complete that the type of understanding he had when he wrote I Corinthians will be like a child. Do you think your own understanding is so more complete than the understanding the apostles in the first century that theirs is childish in comparison to yours? Your interpretation of 'the perfect' in I Corinthians is only a few hundred years old.
The possibility of another new revelation is sealed up till the end of time.
Do you get that from a reference to time being allotted for 'seal'ing 'up vision and prophecy'? Prophecies continued to be given after Jesus died and rose from the dead, so I don't see how you can use that passage to argue for cessationism. After Christ fulfilled prophecy, He ascended and gave prophets to men.
The warning not to add to the book of prophecy, the Bible must be trusted or it simply opens up the air way for the father of lies working in respect to lying signs and wonders which brings a strong delusion form God so that men can believe the lie.
This sounds like a weird, but sadly too common, of a passage at the end of the book of Revelation. If someone receives a prophecy now, that doesn't mean he's adding to the book of revelation, unless he actually adds it to the book of Revelation.
In Old Testament times, not every prophecy from God was added to the Bible. If not all prophecies were put in the Bible then, why would giving a prophecy now be adding to the Bible? That doesn't make any sense at all.
If you know your Bible well, you can probably think of several prophecies and revelations from God that are alluded to in scripture, but aren't included. We read one prophecy of Samuel when he was a child. But apparently he gave numerous prophecies. His words did not fall to the ground and he was accepted as a prophet in Israel. Saul's servant knew he could inquire of the Lord through Samuel to find lost donkeys. But we don't have in the Bible all the other requests of people asking about lost, sheep, oxen, and donkeys (thanks be to God) during the time of Samuel. No doubt, he received many such requests and he may have received revelation from God about it. Inquiring of the LORD through a prophet was specifically permitted in Deuteronomy.
Samuel told Saul he would meet prophets. He did, and they prophesied. What did they prophecy? Show me the prophecies in the Bible. We don't know. The Bible doesn't say because their prophetic utterances aren't recorded in scripture. Saul prophesied, but his prophecies aren't recorded in scripture.
The Bible makes reference to the book of Iddo the Seer, but this book is not included in the Bible and nor are his prophecies. Micaiah had prophesied some stuff about Ahab that he didn't like before the one we read about in scripture. ("He never prophesies anything good about me.") Those previous prophecies are not recorded in scripture.
Paul wrote of a man caught up into the third heaven (which many commentators believe was Paul himself). He saw things that were not lawful to utter. So he got this revelation, but it wasn't included in scripture. The seven thunders said something, but John was not permitted to write it in the book of Revelation.
And the two witnesses prophesy AFTER the last 'amen' in the book of Revelation, but what they say isn't recorded in scripture.
It makes a lot more sense to take scriptural commands and instructions at face value instead of coming up with really complicated, convoluted interpretations to do away with spiritual gifts so we can arrive at a comfortable arrangement where we only have our Bible and our minds and we can know everything and have everything with that. The Bible doesn't teach this arrangement which is so comfortable to the western post-Enlightenment mind.
Rather, we read in I Corinthians that the Spirit gives gifts like the word of knowledge, prophecy, and tongues and interpretation to the church. The Bible commands, Quench not the Spirit. Despise not prophesyings. Prove all things. Hold fast to that which is good. How can someone who believes modern prophecies are from the flesh and/or the devil not help but despise a prophesying when he hearts one? He hears 'thus saith the Lord' and he shuts down. He doesn't prove all things. He rejects the prophecy out of hand. This isn't obedience to the apostolic command.
If any man say today;Lo is Christ thus sayeth the Lord.... knowing the Lord is not adding to His word at the most it makes it to no effect . This is in regard to a tongue that we do not understand or one we can. We are not to believe them.
In that way the elect will not be deceived through the use of false prophets bringing false prophecy.
There is no reason to believe we can or would desire any new revelations ,as if their was a law missing from His book the bible by which we could know him more intimately as evidence of something we can perform.. .
The commandment at the end of prophecy is
not to add it is our perfect safeguard.
Mat 24:23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
Matthew 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Look at Jesus' other sayings. He says that he that receives a prophet in the name of a prophet shall receive a prophet's reward. He said, as recorded in Matthew 23, "Behold I send unto you prophets and wise men and scribes...."
The passage you quote and Matthew 7 warn against false prophets. So a proper Biblical understanding takes all of Jesus words into account. There are true prophets, and there are false prophets. This is the Biblical way to understand it. Paul says that Jesus ascended and gave prophets until we all reach the full measure of the stature of Christ. So there were prophets given after the ascension. The book of Acts also tells us there were prophets in the church. We see the same in I Corinthians. They were to allow the prophets in the church to minister.
The Bible teaches 'Despise not prophesyings. Prove all things.' It does NOT teach that all prophecies are false, so just reject them. The cessationist idea is way off in the ditch, rejecting true prophecy. The other side of the ditch would be accepting all prophecies including false prophecies. In the middle, on the road, is 'despise not prophesyings. Prove all things.'
I can't find a good Biblical case that the 'rules of the game' here in the last days has changed between the time of Paul and our time as far as spiritual gifts go. I Corinthians 1:6 says 'So that ye come behind in no gift waiting for the coming of our Lord Jesus Christ.' Certainly, that includes the very gifts he would address in the epistle.
While we are waiting for Jesus to come back, we should not come behind in tongues, prophecy, or any of these other spiritual gifts.
