No one hear's directly from God. This is stated by those who wish to exalt themselves as prophets, or as on a higher spiritual plane.
If God speaks to someone's heart not to get on that plane, that someone is in adultery, or that he should stop smoking, or that he should be a missionary to central Asia, can't that be 'hearing directly from God? 'The Bible does not have a list with everyone's name with their sin next to it or who is called to what. Would you say that people who hear such things are actually getting messages sent by angels, indirectly from God?
What you propose is not Biblical Christianity. The Bible never makes the Bible the intermediary between God and man. God does speak through scripture, but if we look at what Jesus and the apostles emphasized, they taught about the Holy Spirit. In the New Testament, Jesus is the Mediator between God and man, and He sent us His Spirit. Paul talks about how the Spirit is the earnest, or some translations say 'down payment', of what is to come later. The love of God is shed abroad in our hearts by the Spirit.
Paul also writes in I Corinthians 2
12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God.
(NKJV)
We know through the Spirit. And there are also individuals in the body of Christ who are gifted by the Spirit with different gifts, 'manifestations of the Spirit' as Paul says in I Corinthians 12. Among these are the word of wisdom, the word of knowledge, and prophecy. In I Corinthians 12, after discussing these gifts, Paul points out that members of the body of Christ (of which his readers are parts) with different roles and functions. He teaches that one body part should not say to another, "I have no need of thee." This philosophy of yours--which is not taught in scripture-- teaches people to have that very attitude toward those members of the body of Christ who are gifted to prophesy, have words of wisdom, words of knowledge, toward the young men who have visions and the old men who dream dreams after the Spirit is poured upon them that we read about in Acts 2.
In I Corinthians 1:7, Paul writes, "So that ye come behind in no spiritual gift, waiting for the coming of our Lord Jesus Christ." This was at the beginning of an epistle in which Paul would address his readers about spiritual gifts and in particular, the proper use of speaking in tongues, interpretation, and prophesying in the assembly. Toward the end of the epistle, he writes about the resurrection of the dead and the state of the believers who do not all sleep 'at His coming.' So Paul did not wish that the Corinthians would come behind in any spiritual gift before Jesus returns. We have the time period here during which these spiritual gifts are available.
We should also look in Acts and see that the Holy Spirit can speak to people who are not one of the twelve apostles or Paul. I Corinthians 12 establishes this, but we see it in Acts as well, and this is one example:
Acts 8
29 Then the Spirit said to Philip, “Go near and overtake this chariot.”
(NKJV)
This Philip is later called 'Philip the evangelist'. He was not the Philip of the twelve that Jesus asked who to buy bread from before feeding the 5,000. He was appointed to feed widows. God gifted him to preach the Gospel. So he was what we might call a regular church leader. Ananias who baptized Saul of Tarsus, later known as Paul, heard Jesus talk to him, and he is called a 'devout Jew' and a 'brother'. The Bible never calls him an elder, pastor, deacon, or evangelist.
In your quest to honor the Bible, you should not reject it's teachings.
What should be duly noted is those who say this are always in error doctrinally, while MANY of the same hate the church, and/or speak ill of the Bride, nor do many of them even attend a church.
Are you writing this from the perspective of someone who thinks all his doctrine is right? I just pointed out above where your doctrine on this issue is wrong. All hard-core cessationists are in error doctrinally, so why should we listen to them.
There are people who claim to 'hear God' who are off doctrinally, who are listening to another voice. That doesn't mean we throw the Bible out with the bathwater. The Bible teaches real gifts of the Spirit. There were people in the first century leading people astray. Paul wrote the Thessalonians corrected some false teachings and/or prophecies they had heard.
In I Thessalonians 5, Paul wrote
19 Do not quench the Spirit. 20 Do not despise prophecies. 21 Test all things; hold fast what is good.
(NKJV)
Maybe they had heard so much false prophesying that they were tempted to reject the gift. But we, like they, should obey what is written here. We should not quench the Spirit. If someone prophesies, we should not reject it outright, which would be rejecting a manifestation of the Spirit if it is legitimate. Dismissing them outright out of a false belief that all prophesying ceased in the first century is to disobey verse 20, "Do not despise prophecies.' These verses tell us to test them and to hold fast to what is good.
If it's so they've "heard from God," let's keep writing Scripture, for if God spoke to them it belongs in Scripture because they are saying what they heard is God-breathed.
What does the Bible say about this? Is it Biblical to say that if someone hears from God, it has to be added to the Bible? Clearly not. The Bible refers to many prophecies that it does not quote. I can give a short list-- the stuff Samuel said that did not 'fall to the ground' between that first prophecy he had as a child and when he was an old man who had been leading Israel as a prophet for years. Somehow Saul's servant knew that he could go ask Samuel where lost donkeys were. Samuel gave Saul some details about what would happen. It happened. Saul met some prophets from Shiloh. They prophesied and Saul prophesied. Those prophesies are
not recorded in the Bible. The Bible refers the book of Iddo the Seer. He was a seer--a prophet-- but his prophecies and his book are not in the Bible. Jezebel killed a lot of the prophets of the LORD. Elijah lamented this to the LORD at Horeb. Their prophecies aren't recorded in the Bible.
The Bible also mentions the two witnesses and says they will prophesy and mentions miracles they will do. Whatever your eschatology, that would probably have to happen after the close of the book of Revelation.
