I understand that all spiritual gifts are no longer needed and have ceased; I understand why.  But a question came up with a Pentecostal friend that I need a little help with.  What is the scripture that explains to us that God chooses to no longer speak to people directly?  And what would be a good way to explain why He does not speak to people outside the Bible?
Sincerely,
Trying To Help

Dear Trying To Help,

There are several places that you can go to explain this concept to your Pentecostal friend.  Here are a few verses to show them:

1. We are told that the Bible contains everything we need to know concerning life and godliness (2 Pet 1:3).  If the Bible tells us everything we need to know, we don’t need anything else.
2. The Bible tells us that we shouldn’t add or subtract from God’s Word (Rev 22:18-19).  A vision or prophecy given to an individual would do exactly that.  If a “vision” says more than the Bible, we don’t need it, and if it says the same thing as the Bible, we don’t need it.
3. Heb 1:1-2 says that God used to speak to mankind through many diverse methods, but today He has spoken to us through His Son.  Jesus’ Word is now our only guide.
4. Jude 1:3 says that we have the Word of God handed down “once and for all”.  God has finished providing revelation to us.
5. The silver bullet verses are 1 Cor 13:8-9, but it is a little lengthier discussion to handle all of the arguments in that verse.  We recommend you read “Incomplete Understanding” for a complete breakdown of the 1 Cor 13:8-9 argument.

The long and the short of it is that prophecy was needed until the Bible was complete, but now that we have everything God wanted us to know, prophecy has ceased.   SB
